How to build a POTATO LAUNCHER

thomas the lover says: Mar 24, 2009. 4:54 PM

Dude DO NOT PUT THE propellent IN FIRST .You could nudge the ignition while trying to get a spud in and BYE BYE HAND thats rally dangerous. plz for your own safety put the propellent in last .

So many safety issues! And it was kind of a weak launch...

Though you wont get nearly as much power by putting in the propellant last.

Whats the farthest launch you've had

Please Friend! I beg you to tell me how to create the spark ignitor you created. I could'nt figure it out. Please I' m in a desperate need for such a great one. Science fair is near and i don't know a way to create an eco-friendly ignitor like yours

just a tip never combine whit pvc and black pvc it could end up being faulty and u might blow your face off just incase you didnt know the the two dont stick

DO NOT ,I repeat, DO NOT EVER PUT YOUR IGNITOR ON THE END CAP! This is for two reasons One, It weakens the integrity of the end cap Two, If you drop the gun on its end , it may fire accidentaly!

oh wait i get it sorry! i actually used a flint and steel lantern ignitor for mine! it turned out really nice!

Im thinking of making my first instructable and it will be how to make a potato launcher out of 3 things you would need a hollow pipe, a potato and a pipe which isnt hollow
Get the hollow pipe and push it into the potato which will make a peice of potato which looks like a shotgun shell
Do the same with the other end, so both ends are plugged with potato's.
Now get the not-hollow tube and push one bit of the potato near the other and the air pressure will build up and fire one bit of the potato, if anyone try's this please tell me the results because as soon as i get the peices i will make an instructable!

i read this comment last night and then tried it today the results were shameful i filled a pipe with silicon and pushed it in to the slightly bigger pipe and it went only about 5 metres which is good but then when i droped it from my balcony solid pipe towards the ground it went about 15 metres in the air so your idea did work but only when taken to a slightly bigger scale then my friend was happy with wat had just happened so we put it on a fence post and lashed it there really tight then we tied a car tire to our paddock basher and drove at the solid pipe end and it went about 60 metres so it worked even better on a heaps larger scale kudos to you on your idea

hey thx now i would make my first instructables!!:D yeahh ... kinding jeje but you better dont say your ideas too fast, somebody can stole them ·_· jeje

doubt it would be very effective. you'd have to have a really good seal and a large chamber.

Here is a cannon I made using general guidelines from your video. Thanks!

neither am I! i just made the mistake of thinking you were! sorry

When i made the video I knew that a George Bush mask would be funny, and that a lot of people were mad at him. I would do the same thing with a Obama mask...maybe I will some day.

Thanks for watching.

your welcome! i actually made a potato gun almost exactly like this, i too used a flint and steel sparker to ignite mine, but i put racing strips on the combustion chamber! it looks awesome! here is a link if you would like to see:http://www.youtube.com/watch?v=O6x7Y-QrDLs

thanks! Levi

supamunki says: Nov 3, 2009. 11:45 PM

NIJU! says: Aug 6, 2009. 5:34 AM

hehe, the igniter fluid looks like WD-40. good instructable though

Indeed it is.

omkar_hummer says: Oct 25, 2008. 12:58 AM

ChappyShowcase (author) in reply to omkar_hummerOct 28, 2008. 2:35 PM

I bought a whole bunch of them years ago at Orchard Supply.

DWV, isn't really suitable for spudguns because it doesn't stand up well to pressure. I wouldn't be at all suprised if your reducer blew out, shooting shrapnel everywhere.

check out www.spudfiles.com for more detailed (and safer) walkthroughs

Thanks for letting me know. I guess I have been pretty lucky up to this point.
