4 mil plastic sheeting
iron or flat iron
food coloring or glitter (optional)
I started with 9’x12′ 4 mil plastic sheeting and cut in half. We had just little guys so I thought I’d save half for another day. You could use the whole sheet, but it will take a lot of water.
Fold your plastic in half.
Starting a couple inches in from the folded end fold your parchment in half and place over opening.
Turn off the hose and remove. Close off the opening with a couple pieces of duct tape.
