Introduction: MRE Bombs

The watter mixed with the MRE Heating Pack makes gasses, the gasses expand the bottle to the point of breakage, so when the bottle "Decompresses" it sounds like an explosion simple since here... But loads of fun!

Please excuse the Number of steps, its easier then you think.

Warning - Use at own risk! The gasses from the MRE Heating Pack is very flammable, so I strongly suggest keeping it away from a open flame..

Also, Check with you town law to see if it is legal!

Step 1: Things You Need

You will need --

1-2 MRE Heating packs (use more or less for size of bottle i suggest one or two for a 18-24oz. bottle)

Plastic Bottle with screw on Lid

An some water.. (OH NO NOT WATTER!)

Step 2: First

First off, you open your MRE Heating Pack, and take out the actual heating package.. Make sure you can get outside fast, the last thing you want is for it to go off inside. But no worries, it doesn't become active until it comes in contact with a liquid.

Step 3: Secent

You can do this step many different ways, experiment and find the easiest to you, this is the method i use..

You rip the Heating stuff into long thin strips. an well you put it in the bottle.. (MY GOWD... ITS SO HARD!)

Step 4: Step 3!

Well... here is the hardest part of all... (haha doesn't get much harder then that last step eh?) But this will take the longest time to master... You add just enough water to cover about half of the MRE stuff... you can adjust to how much you use an what not it takes time to figure out how much u really need... but as soon as u add the water you put the cap on and make sure its nice and tight. then you take the bottle outside an shake well... once it starts to get hard you place it where u want and stand back and watch

Step 5: Just Stand Back an Wait..

Well... this is easy.. just watch.. i would suggest standing about 10 or more feet away.. The time for the decompression differs between bottles an how much u use and what not.

Unfortunately i didn't get pictures of when it was "Decompressing" because i was to occupied RECORDING IT!! Yes you get to see how cool it is before u go out an do it yourself! I cant figure out how to add the video here.. so.. here is a Hyper link to it on Myspace.com http://vids.myspace.com/index.cfm?fuseaction=vids.individual&videoid=922650088&n=2

But here are a few pictures of the bottle afterwords

Now, Here is how to make it explosive... Remember how I said keep the fumes away from fire.. Well.. find a way to have it blow up by the fire an BOOM... Well, there ya go.. (Once again i am not responsible for anything you do with this)

Enjoy
Results my very..

    this is cool man :)

    What happens if you throw it in a fire, and what's the chemical reaction going on?

    It all depends on the pressure, When plastic reaches a certain temperature it will start to either Melt or Shrink. If the Compression on the inside is great enough then it will "Explode" and if that happened the highly flammable gases on the inside will light on fire there for creating more of an actual explosion. I don't know what gases the heating pack puts off all I know is it is highly flammable.

    Any idea what chemicals you are mixing, nice name by the the way, loved Death Note.

    No, If I had any heating Packs left I would just check the package, Try Googling "MRE Heating Pack" and see what you get. Never Played/Watched Death Note, I Randomly came up with Ryuk, and Antonio is my Name so *Shrug*

    Oh, sorry. Good name either way.

    You do know that you can get the SAME effect 1: cheaper & 2: faster with dry ice and water in a soda bottle. Then yor aren't wasting a nice MRE :D Cool idea though

    Well, unfortunately people under the age of 18, if im not mistaken, cannot buy dry ice. Therefor we have to have a replacement. And it helps that i have 2 boxes worth of nothing but the heating back we jacked from some old junk yard buy sheer luck!

    thats why you take your c02 tank (from paintball) put a bag over top and hold in the button. instant dry ice :D
