this instructable is how to make a Kinetic Sculpture using everyday household items
Step 1: REINFORCE!
put the duct tape around the top edge of the plastic bag so it does not rip when you have to put the tennis ball through it
Step 2: 2-WAY BAG
rip a hole in the non reinforced end so the tennis ball can get through (you can reinforce this side if you want)
Step 3: TABLE+DUCTAPE= STRONG HOLD!
tape the reinforced side to a table so you don't have to hold it there and you can remove it so it is not permanent
Step 4: Easy Step of Awesomeness
place books under the plastic pretty easy huh?
Step 5: Easier Step of More Awesomeness!
place cardboard on top of books so one side is higher than the other
Step 6: THE FINAL STEP
drop the tennis through the plastic bag and then it should fall and roll on to the cardboard then land on the floor! (VIDEO INCLUDED!)
