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

It's a good start but I'm not entirely sure what you're making, is it a basketball hoop for tennis balls? I think it may need more of a description but it's a nice start.

it is not a tennis ball hoop it is a Kinetic Sculpture where you drop a ball through a bag then it hits a piece of cardboard and rolls off
really useful
