Picture of 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.



Step 1: You will Need

A Sharpie
Canned Air
Electrical Tape (Substitute Packing Tape)
Ball Point Pen
Rubber Band
Bottle Cap
Leatherman
Robot Sticker (optional)

thats not liquid fuel
you're right, liquid fuelled rockets carry a fuel and oxidiser that react through combustion to produce an explosion and generate thrust. the instructable should be renamed compressed gas rocket. overall it is a good tutorial though.
Eh...... not an explosion. A (hopefully) controlled deflagration.

WOW, where did you get the instructables sticker?
Thanks!!!
I can't find them anywhere either.
Win a contest no mater how small.
might wanna wear leather/rubber gloves for this; you can easily get frostbite if you get sprayed with that stuff.
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)
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.
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).
my freind spray some in my mouth D:
My doctor used this stuff to remove a wart on my hand, even though local anesthetic was applied to my hand, it still hurt like crazy.
And here I am turning the can upside down to freeze stuff :P
That is how I kill spiders around my computer.....

ugh in california you have to be 18 to buy a can of the compressed air...wtf?!
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."
That blade thing is completely false. You can legally have any length blade you want, it's just illegal to "conceal" fixed blades.
drozzle Phade4 years ago
You are also false. You can own a blade of any length but you cannot carry one folding or fixed over 3 inches long.
If your under 18 u can carry a knife no bigger than the palm of your hand
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.
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 :)
In Australia, if you don't carry a knife around with you, then you'll get raped by dropbears.

there was a case where kids were inhaling the air and getting high off it
IceAnubis goeon4 years ago
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.
goeon IceAnubis4 years ago
Damn. Thats... terrible
Wesley666 goeon5 years ago
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
I still hate those kids
 Heh Heh Heh
Redgerr goeon6 years ago
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
goeon Redgerr6 years ago
yeah
get it off ebay with ur dad's account.

@shadow123456: and THAT is why you build a hand held launcher!
do any of youse still have a hand
one blew up in my hand almost tore my finger off
jake4a44 years ago
I found a huge can at walmart that doesn't do anything if you spray yourself as much as you want.
Don't see why you'd spray yourself in the first place?
Ariskis jake4a44 years ago
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.
