You'll need flour (in this picture I had wheat flour because I thought it may work, but it DOESN'T- not at all- don't even waste your time!!), water, a balloon (preferably a punch balloon because they're actually round) and elmer's glue (or ModPodge, which is what I actually ended up using in the final go 'round)
The balloon had this "sticky out thingy" on the bottom for the rubber band to go through, so I took the rubberband out and taped the "sticky out thingy" down.
The paper mache is one part flour, two parts water and about 1/2 part glue/ModPodge. This picture is when I was using the wheat flour and it's nasty looking. The white flour was much smoother.
Take strips of torn up newspaper and dip them in the paper mache'. Then apply them to the entire balloon, leaving an open area (I traced a kids cup on the top of the balloon to use as the guide for the opening) to put the candy in later. Let it sit and dry (or mostly dry, if you're impatient like me) and apply another layer. I did 3 layers total and it was pretty strong. I wasn't sure the kids were going to break it. On the bright side, we got through all kids taking 3 swings each and got back to my son (birthday boy) so he could try until it broke. (This is good, because anyone with a 4 year old knows that they like to be the winner! Or maybe it's just a boy thing. Or a kid thing...)
After my pinata set under the ceiling fan all night, I painted it with a few coats of craft paint and decorated it with a marker to make ball laces. I filled it with tons of goodies and used a hole punch to put holes around the goody hole so that I could thread ribbon through to make it "hangable". Then we hung it from a tree and went to town!
Till it burst open and everyone made a mad dash for goodies!!!
Here is the finished "prehitting" pinata again. :)
Hope this can save you a few $$ at your next party!
