How to Make a Leak Proof Water Blob (without tape!). We did a blob last year. The kids loved it. And it leaked. I looked over how she does it (iron-genius!) and am excited to give it a try. We added glitter to our water to make it a little more fun.
DIY water blob was such a HIT at our backyard birthday! Purchase plastic sheeting (from Lowe's) and seal the edges with duct tape...fill with water and poof...you have a fun squishy water blob! I inserted some foam shapes before I sealed the blob...next time I might put glitter and food coloring in the water!
