Step 1: Gather Materials
Flour paste is made by whisking flour into water. That's all you really need! I like to add a but of white glue because I think it improves the finish, but that's up to you. You can make the paste as thick or as thin as you like; I personally like mine a little bit thick, sort of like pancake batter.
I used one large punch-ball balloon (those giant ones that come with a huge rubber band) and two tiny party balloons. You will also need duct tape, masking tape, and a hairdryer would be handy.
