Office Supplies Challenge; Liquid Fuel Rocket

Office Supplies Challenge; Liquid Fuel Rocket
Liquid Fuel Rocket made from office supplies. Warning, this is kinda dangerous, I had one blow up in my hand already, it was more startling than anything, the two halves flew off in different directions, (wear leather gloves just to be safe.). But they'll fly about 75 feet straight up.

I found a huge can at walmart that doesn't do anything if you spray yourself as much as you want.

If you turn it upside down it gets dangerous because the regrigerant begins to come out.
Aug 17, 2011. 11:46 PMKevinAlien26 says:
Don't see why you'd spray yourself in the first place?
Feb 18, 2011. 3:40 PMChibichuba says:
It depends on the type of the can and chemicals inside. If you can find that brand, let the author know so the builders can try it out.

WOW, where did you get the instructables sticker?
Thanks!!!

I can't find them anywhere either.

ugh in california you have to be 18 to buy a can of the compressed air...wtf?!
Apr 4, 2011. 10:16 PMgeodez says:
In california you can't own a knife with a blade over 3" or a magazine with a capacity over 10 rounds. That's modern americans for you, caring more about celebrities than, just about everything else unless it is "dramatic," or "popular."
Jul 7, 2011. 9:50 PMPhade says:
That blade thing is completely false. You can legally have any length blade you want, it's just illegal to "conceal" fixed blades.
Jul 12, 2011. 4:02 PMdrozzle says:
You are also false. You can own a blade of any length but you cannot carry one folding or fixed over 3 inches long.
Aug 17, 2011. 11:43 PMKevinAlien26 says:
If your under 18 u can carry a knife no bigger than the palm of your hand
Aug 27, 2011. 1:28 PMPhade says:
If you guys don't know what you're talking about don't post. In California it is legal to carry a folding blade as long as you want, same goes for fixed blades but the fixed blade must not be concealed.
Aug 27, 2011. 2:49 PMKevinAlien26 says:
I didnt say anything about fixed or concealed or anything o that sort. Just thought I'd let you know what the security gaurds at my old high school told us (California) so no need to get mad bro :)

get it off ebay with ur dad's account.
Jul 2, 2009. 7:09 PMgoeon says:
there was a case where kids were inhaling the air and getting high off it
May 8, 2011. 1:12 PMIceAnubis says:
I can understand the fear... I'm a resident advisor in my school, and I found the corpse of a guy who inhaled the stuff until it killed him. Not fun.
May 12, 2011. 6:03 PMgoeon says:
Damn. Thats... terrible
May 2, 2010. 7:59 PMWesley666 says:
Ya, and they died.  It has refrigerant in it which is heavier then air and no oxygen gets to your lungs and you die.  Kids can still buy it in Canada though! :D
Apr 12, 2010. 6:50 PMMrMadmonkey4 says:
I still hate those kids
Apr 12, 2010. 6:54 PMgoeon says:
 Heh Heh Heh
Jul 17, 2009. 12:57 PMRedgerr says:
many of them infact... there are some places(if i remember correctly) where you can get it though because its 100% oxygen(or somthing), they are more expencive and last shorter
Jul 18, 2009. 4:12 PMgoeon says:
yeah
Aug 14, 2011. 1:15 PMLord Jon Bigglesworth says:
I love how there is a whole conversation of replies to the comment: "Be careful or you can get frostbite."
Aug 13, 2011. 9:38 PMyoshie257 says:
I put random eletrical tape on the grey part and spray painted it black then removed the tape its like a tiger
Apr 5, 2011. 2:51 PMmrwaffles2 says:
how do you make the wings i dont get it
Jul 17, 2011. 3:31 PMdeobomb says:
you fold the tape into them
Apr 16, 2011. 6:43 PMbendog38 says:
watch the vid
Jul 9, 2011. 11:28 AMDannytheGreat says:
the meat tenderizer wasn't listed in what was needed
May 19, 2009. 5:52 PMshaneomacmcgee says:
might wanna wear leather/rubber gloves for this; you can easily get frostbite if you get sprayed with that stuff.
May 9, 2011. 10:10 AMKasm279 says:
And here I am turning the can upside down to freeze stuff :P
Jun 5, 2011. 12:28 PMjmontgomery3 says:
That is how I kill spiders around my computer.....
Apr 24, 2010. 7:45 PMPizzapie500 says:
True That!!! I got it onto my finger and it hurt sooooooooooo badly! That finger was numb for days and skin fell off!! Also never shake the can!! I did and frost appeared on the outside of the can! (actually it might not be frost, but the can was very cold)
Jul 13, 2010. 6:48 PMCheezpaper says:
Didn't hurt that bad for me... And it definitely didn't cause any damage after spraying my finger for 10 secs.... You're probably just overreacting.
Jul 19, 2010. 1:18 PMPizzapie500 says:
Did you get the white stuff onto your hand? What it does is expand and freeze. So if it gets onto your hand it'll stretch your skin (make it peel off) and it'll give it frostbite (make it numb).
May 30, 2011. 7:01 AMdylankunaikennedy says:
i might make one but without the fying art and just use it as an ordiment :)
May 8, 2011. 2:16 PMKasm279 says:
Using the office duster stuff for fuel is a TERRIBLE idea. Why? When burned it turns into a compound (that I cannot remember the name of) that when contacts water, turns into hydrofluoric acid. What are you lungs full of? Water...
May 9, 2011. 6:16 AMIcedZ says:
It's not being burned.
