Kids love experiments, so their challenge today was to find out if they could poke a pencil (or 10) through a plastic bag full of water, without it leaking. They did really well, although of course it was an outside experiment!
@alinz Yes - lots of pencils can be put through the bag and the plastic molecules all try to hold hands around the pencil, creating a seal, so it doesn't leak. Yes @julzmaioro - taking one pencil out is enough to cause a shoe-wetting, squealing shambles in the middle of the lesson!
