Can you poke a hole in a bag full of water without losing even one drop? Once you learn the science behind this leak-proof bag experiment, you’ll be ready to poke holes in a bag full of water while holding it over somebody’s head! We filled the zipper storage bag about 2/3 full of water.

Start the leak proof bag experiment by asking kids a simple question: What happens when you poke a water-filled plastic bag with a sharp stick or pencil? They’ll probably say there’s going to be a hole in the bag, and the water’s going to leak out of the bag. Materials for Leak proof bag experiment.

They were messy because white glue… BEADS – This little bag will last forever. BALLOONS – Many bags of many colors. The back-story of that challenge is to build a flood-proof structure for a dog house. I have only had one pen leak a big mess. We use these for robots and the animal adaptations challenge.
