Introduction: 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
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
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 2: Popcorn Machine
what you need:
make the can; draw a triangle on the can like in the picture and cut it out like I did
make the holder. get the tealight and tape the 4 nails around it
put the mixture in. 2 teaspoons of corn and 1 teaspoon of oil
the rig; put the can on top of your nails
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!
