Introduction: Several Uses for Old Cans

Picture of Several Uses for Old Cans

have any cans lying around? then don't just throw them away! recycle them!

I will let you see some awesome ways to use your cans!

Step 1: Make a Fire

Picture of Make a Fire

yes that's right! make a fire!

this is because the back of a can is a perfect parabola, that means you can focus light with it!

you will need:
a piece of chocolate
piece of paper
sunny day

step 1.
rub the chocolate over the bottom of the can until it reflects good

step 2. go outside and focus the sun with it on your piece of paper

step 3.
have fun

Step 2: Popcorn Machine

Picture of Popcorn Machine

what you need:
vegetable oil

step 1
make the can; draw a triangle on the can like in the picture and cut it out like I did

step 2
make the holder. get the tealight and tape the 4 nails around it

step 3
put the mixture in. 2 teaspoons of corn and 1 teaspoon of oil

step 4
the rig; put the can on top of your nails

step 5
the popcorn; light wait add salt and enjoy!

Step 3: Make It a Target

this is actually quite familiar with those airsofters out there...
but for those who don't know:

put a can on some spot at about chest height

shoot it off

another use for a can!

bb guns and airsoft are about the same if you shoot someone with a gas airsoft gun it has about the same power as a bb gun

pinto505 (author)2008-09-17

BB guns shoot metal bb's and a typically more powerful. airsoft use plastic BB's.

dunnos (author)pinto5052008-09-17

okay, thanks

grut125 (author)dunnos2008-12-21

airsoft guns shoot plastic bbs. and BB guns shoot metal ones but if you have a air cannon you cann shoot any thing you want, like a stapler, cellphone, or a jackknife.

rbneville (author)2008-08-15

dunnos (author)rbneville2008-08-16

i dont really know the difference between airsoft and bb but they are about the same

Rudrarup (author)2008-05-12

Maan! its really green! Good Job! Liked it!

theosullis (author)Rudrarup2008-07-23

Im very green myself yet found this very handy.

There's no way that this Instructible legitimately got something like 46 votes. There's only eight comments and less than 500 views. This can't be right. Not bashing the author here, I'm just confused...

lawizeg (author)Firebert0102008-04-07

Ah, its someone voting with lots of accounts. If you notice who voted for him, the account names are all random numbers.

dunnos (author)lawizeg2008-04-07

but everyone got like 40 votes i guess there is some1 who wants to screw up this contest

fungus amungus (author)dunnos2008-04-09

Don't worry about the fake votes. They all get tossed out in the end anyway.

dunnos (author)fungus amungus2008-04-11

where can i see how much votes i have??

fungus amungus (author)dunnos2008-04-11

Right now, nowhere. To prevent people from trying to skew the top votes list with fake votes, we've hidden it away. We'd prefer that people focus on the quality of each instructable than if people are cheating.

dunnos (author)fungus amungus2008-04-12

but i wanna brag by my friends how much votes i have =[
could you please make something that you can see your own votes?

Maybe Instructables should oversee the next Presidential election...

PKM (author)lawizeg2008-04-08

Oh man, there's enough vote-rigging in the news to worry about it here as well. Can you see who has voted for it in a competition? I see the 5-digit-number-obvious-vote-rigging profiles that have given it a + but can't see where the competition votes have come from. Are they anonymised? In any case, I guess it will just be a case for the mods.

cheating-master (author)2008-04-11

cool, great Instructable man :)

DaNerd11 (author)2008-04-08

Where do i cut the triangle in the can for the popcorn maker? Great idea.

dunnos (author)DaNerd112008-04-08

Or you can just take the can to the recycling center.

mikedoth (author)2008-04-05

I made a thin can into a incent burner, thinking of making an instructable for it as I got tired of the mess the cheap wooden ones produce.

Firebert010 (author)mikedoth2008-04-07

Please don't. No offense, but there's already one.
