You know that trick, right? If you put mentos in a cola bottle (plastic, not the glass bottles) it'll spray all over the place. If you're fast enough, you can close the bottle and you'll have a Cola Bomb. Just throw it at the ground or anything hard and it'll explode.

Anyone of you have tried this (heh someone probably did) and have you found an "optimal recipe" for max explosion results?

Hmm... to think that John Wilkes Booth may have a backup weapon to kill Lincoln with.

I know what I will be doing tomorrow.

he he

You won't be able to really blow up things except for the bottle. I've made some sort of guide to doing it here.

I'm going to tape it tomorrow

If you want to make an explosive bottle, and have a fair bit of patience, do this:

Get a glass juice bottle, once with a pop bubble lid.
Drink it.
Fill it with boiling water, and quickly put the lid on. The less air in the bottle, the better. But a little bit (the amount under the cap) won't hurt.
Put it in the fridge overnight.
Put it in a snowbank outside.
Let it get about -35 or better below.

Tada: Instant proximity mine, and the colder it gets, the more unstable it is.

P.S. I don't recomend actually setting this thing off, as the few times I have done this, the needle shaped and sized glass shards have a range up to 5m depending on the amount of air in the bottle. The mode distance is about 2m, with very little variance.

The stronger/thicker the glass and the more water you can supercool the bigger the explosion.

I know one.If I remember this right.
You need a glass bottle, "the works"(i don't know why exactly this brand but I remember that it was told like this) bleach (or is it toilet cleaner)and foil. Make little balls of foil and stick them in the bottle to fill ,um let's say 1/4 of the bottle.Now you have to be quick-pour the bleach/toilet cleaner in the bottle,close it tightly(somehow) and give it a shake.When the bottle starts getting hot THROW and run!

Never tried this myself,but i've read it somewhere

RS what up, those are draino bombs. i used to make those all the friggin time when i was a kid and if you do it right they are pretty dang loud.

what you need is the crystal kind of "draino" and little balls of foil and add water, or this stuff called "the works" which does not require water, all you do is put in the balls of foil first, pour in the stuff and cap it up.

and dont do it on your grass cause it will kill it

i remember doing this in high school with "smarties" or "spree" etc the american kind of "smarties" cause i was trying to explain what they were to someone from austrailia before and the smarties they have there are apparently what we call "m&ms" or "reeses pieces" or something but yeah i remember making those

Yeah, outside the US they're like bigger M&Ms. They don't taste as good though.

i dont know if this will work i thought of it just now
if you get a plastic bottle and then put some vinager in it let say about fill it up about 4/5s of the way with it then put in about 1 or 2 big spoons of baking soda and close the lid real quickly then shake it up a bit then throw it realy hard it should work cause baking soda and vinager fizz up when put together if you try this please tell me if it works oh and to get colored explosions put food coloring in it before you put the baking soda in it would look cool and if you throw two different colored ones at the same time you might get a two colored explosion it should work and even if it doesnt you should still stand clear of the splosion
try it and tell me if it works

It may kill the grass, but it can also kill you. Large plumes of something with a fairly low LD50 just can not be all that longlivity inducing.

you mean if you inhale it? or eat it? yeah that would probably kill you. and if you put it on your skin and add water you get one of those sweet scars like in fight club. *kiss* whats this? this is a chemical burn

are you talking about my idea cause i dont know weather it works or not
has any one tried it yet

did it work cause i didnt try puting vinager and baking soda together in a bottle to make a splosion

it would probably blow up if you threw it like when you put smarties in coke, thats my guess

I don't know if this really works, I just found it on a website.

Ok, find your worst enemy, then dare him/her to eat 2 bananas as quickly as he/she can, then chug down a can of sprite. After that, they will have the intense pain of the mixture coming out their mouth and nose.

Wonder what would happen if you could put a cap on them...

IF you get just the righ mixture and then put is in an orange gun you've got yourself a really kool way to shoot exploding cola bottles at ppl

ahh the good times

step one;
get some poly styrene and some unleaded petrol
step two;
mix it together
step three;
wait a while till it forms a gel
step three;
put it in a bottle
step four;
use a bike pump to commpress the air in the bottle
step five;
make a fuse out of some candle wick and oil
step six;
put on the fuse (recommemd 1meter) then light run and hide behind somthin
step seven;
look at the pretty colors

not as dangerouse as it sounds just alot of fun
and if you make the gel right it glows

That'd be napalm, unless petrol is a lot different than gas. (Was petrol the english name for gasoline? I forget)

I'm not loggin in, 'cause I know kyle is keylogging this.

But if you add more and more styrofoam (I think) it gets more and more napalm-like. Optically, and Chemically.

Yeah, petrol = gasoline

one foam esky+litter of petrol/gasoline=really close to napalm

i did that like a few weeks ago in a glass bottle that was from pomegranate juice so it said "POM" on the bottle with a heart for the o it was kinda funny

Fill a bottle about halfway up with water and calcium carbide. THIS IS EXTREMELY DANGEROUS since calcium carbide + water produces acetylene, and
1. Acetylene explodes when it is put under a pressure greater then 1 bar.
2. Acetylene + oxygen is VERY unstable and can explode anytime you don't want it to explode.
3. Acetylene is just a tiny little bit less powerful then hydrogen, and they use that stuff for launching space shuttles. Go figure.

Don't try this at home. I didn't tell you not to do it anywhere else.

That sounds fun

Hey, there's nothing wrong with acetylene torches.

I figure my best 1-man-army gear would consist of:
Bike, with trailer n' food, capacitors, pedal generator and stuff
Shoulder mounted, ranged, focusable emp gun. With scope
Acetylene torch
"The" (massive) chain, for towing said stuff, and as a melee weapon
Crossbow

I figure I could take the world, if they don't find me.

Thanks for all these recipes guys...plus I have lots of drinks that use relatively large glass bottles like Sobe.

Hey, does anyone know where I could buy a pack of electronic parts so I could experiment & stuff? Radio Shack doesn't sell packs .

I wanna attack my enemie's phone.
</Unrelated>

I had a friend who made a pseudo-EMP device. It could fry pretty much every electronic gizmo in a room.

Sounds like something Chrispy might know. He was really into blowing up things with tesla coils

Are you saying that there is something wrong with tesla coils?

Tesla coils are freakin great. I made one last year...where did I put that thing..hmm...

What is a tesla coil and how does it work?

Rember those Zappy things in Command and Conqure

Yup, just the same, 'cept they'll zap you too.

I didn't try making one because it has EXTREMELY high voltages, enough to fry you even more than the flames of Dink Hell.

Ususally the amperages are right down low, so the voltages just fly across the dead skin layer, not doing much damage. But if the amperage gets a little too high, you get something like spiderweb scars appearing after a week or so. In addition to the brain damage, heart palpatations, nerve tissue death and other assorted ailments.

It's a rather confusing matter, isn't it?

V=IR, so shouldn't higher voltages result in higher amperages? I know human skin isn't ohmic, but I've played with non-ohmic resistors before, and the general relationship is still that an increase in voltage means an increase in current, so I don't get the whole "all that matters is the amperage" thing.

All I know is when you use a transformer and such to up power you lose amps, basic law, you have to give some to gain some.

P = V*I...

And P is all that matters. So shove that resistance way way up.

I'll finally be able to actually figure out what my devices here are doing, and if they are doing what I think they are doing, after I'm done this physics class next semester.

I'll tell ya another great formula:
W=Q=U*I*t=I^2*R*t=P*t
It means that the heat(Q) is equal to the energy(W), which is the electric power(P=U*I)*time(t). That means that more you let an object to be passed by electricity, the more heat he gives.

W is work.
E is energy.

I often confuse them, but they're different...

I study in Romania. Here, W is electrical energy, and E is mechanical energy. L is work(in Romanian, work means "lucru").

How to get formulaes make sense: Stop using those nonsense one-letter values.

ye

When you have a simple formula, you can stop using these nonsense letters. Did you ever sloved a real difficult phisics problem? There you have to fill pages with nonsense letteres. How can you slove the problem without letters?

Those letters are quite logical if you have quite some knowledge of physics... But if you don't know these letters this kinda looks nonsens.

Most of those letters are like abbreviations. So they're quite logical. Most of the time they have a meaning.

Like:

F is Force
m is mass
a is acceleration

So you have the formula F = m*a
It simply means force = mass * acceleration.

But if you look at cypry's formula it would become way to long to write in that fashion.

You think that was long? You know Khirchhoff laws? Especially the second one. You want to write that in words?

The time you spend to read that equals the time you use to figure out what all those letters stand for. And when it's written with words it's a lot simpler to perceive, unless you're very familiar with chemistry.

Except we're talking about physics, and not about chemistry

You get even more lettercombinations when talking about chemistry (when talking about elements).

So we'll stick with physics.

(I'm afraid that was just the thing needed to bring the subject to chemistry though )

Well this thread was about chemistry at the beginning.Sorta

I gottta say that my favorite letter is P. For momentum.

We always use p for momentum. P is power (and something else, too... mayber pressure?)

Perimeter

p = momentum and pressure
P is power.

To make a difference between the momentum and pressure p's, I draw an arrow on top of the momentum one to indicate this is a vector.

In math, p is semiperimeter, the half of the perimeter. In phisics, we use P for power and pressure. We use M for momentum(in Romania).

To revive the orginal topic, I've never heard of the mentos and cola method. I wonder if it would work better with plain soda water. That seems a little more powerful (based on how often it sprays all over just from opening the bottle).

But I've done it with dry ice and a number of times. It's without a doubt the best non-pyrotechnic way to make a really loud explosion. I don't throw it though -- that's too risky for my taste -- I just use enough dry ice that it blows up on its own. (So it's a time bomb instead of a grenade, if you will). So long as you do that (and put it somewhere it can't hurt anything) it's really pretty safe. Do expect alarmed neighbors to come out of their houses look around though...

Oh, and the there's no need to sacrifice cola, the dry ice is more than capable on it's own. You can just use water, in fact it's easiet if you put the dry ice in first.

So it goes like this:

1. Put dry ice in bottle. (1/4 full or so)
2. Add enough water to cover dry ice.
3. Screw on cap.
4. Stand back.

wtf... your training everyone to be terrorists lolo...

I wonder if vinegar+baking soda could blow a bottle.I think not

Water with Alkali metals give a nice explosion too. It's quite hard to make the metal touch the water no earlier than neccesary though...

I wonder if vinegar+baking soda could blow a bottle.I think not.

I donno, but if anyone wants to try, I (rather unscientifically) determined the correct proportions to be 1 Tablespoon baking soda per Cup of vinigar.

Water with Alkali metals give a nice explosion too. It's quite hard to make the metal touch the water no earlier than neccesary though...

Heck yeah. I'd love to try that but I don't know where to get any. The government (and eBay) seem to be cracking down on the sale of sodium to the public. If you want to see some great videos of people having fun with sodium, though, look here (great site BTW, look around a bit).

why stick to proportions

more gives more

Not if you're using the correct proportion to start with. Say 1 tablespoon baking soda uses up the whole cup of vinegar. Adding more soda won't do anything, as there isn't enough vinegar to react with. Adding vinegar doesn't do much either, as you've now got too few soda.

Exactly. By all means top off the bottle if you can figure out how, I'm just suggesting you use that ratio, which could also be expressed as 16:1 (by volume).

If anyone's interested, I determined that while doing a somewhat more subdued baking soda and vinigar expiriment. You know that kind of hand warmer you set off by bending a little disc and then boil to recharge? It turns out they use sodium acetate which is what you get (along with carbon dioxide and water) when you mix baking soda and vinigar (preferable distilled). If you boil it down to a kind of thin syrup and put it in a little jar you've made your own hand warmer. I don't know how to make the disc, but you can just dry some of the solution out to get a starter crystal instead.

Francium is almost impossible to get.

But I don't believe it's impossible to get your hands on the other alkali metals...

Yeah or gunpowder+gasoline+fertilizer+fire could maybe make a big explosion... I dont know can anyone back me up on this?!

I believe that gunpowder + fire makes an explosion. Gasoline + fertilizer + fire does the same, (just somewhat stronger). But I don't know how good they work together (I mean gasoline + gunpowder).

I think that it's an interesting mix

Interesting... Yes, but I thought that the reason that gunpowder explodes was that it is a powder. If you make a solid block of gunpowder it won't explode. (Unless you cover it perhaps)

But I might be very wrong, and the gunpowder might act like an accelerator (like gasoline) and make the fertilizer explode even more powerfull.

No, it would be more like fireworks.

Meh, if you want to make things explode, the way to go is nitro, pure and simple.

Gunpowder only makes an explosion when it's pressed.If it's loose it will just make a burst of flame.
I think if you mix shoote with gunpowder, there should be a biger part of gunpowder

wanna now the funny thing,, the first topic of this was metos and pepsi, lol

i tried the mentos and coke twice...failed both times...to slow maybe...video with dry ice was cool...gonna try mentos and coke again soon...

I hope you did notice that the coke starts to bubble. If it didn't, make sure the gas that escapes when you open the bottle is at a minimum.

wanna now the funny thing,, the first topic of this was metos and pepsi, lol

Which was a much better title because spilling the Divine Drink® is one of the last thing I would do.

A bright Scot in the SAS came up with the MRE bomb.
MREs (Meals Ready To Eat) become hot with the addition of water. They are used by American soldiers.
So he was out fishing. Being bored, he tried to find something to do. So he stuck a MRE pie into a Coke, screwed on the lid, chucked it to the shore, and then cackled gleefully at the destruction of the bottle and the pire-coke mix scattered everywhere.
Later on, he used more indecent liquids against the privates...

I really have no relevant things to say other than the fact that I have lived off of MREs for quite some time...I have power...they just much easier than fighting with old ladies at Walmart over a can of alphabet soup...
