Leak-Proof Bag – Kid’s Science Experiment

Leak Proof Bag Experiment

Here’s an awesome and extremely easy Kid’s Science Experiment – the Leek-Proof Plastic Bag!!

I’m sure you have everything you need at home – 

  • Plastic Zip Lock Bags
  • Sharp Pencils
  • Water

Instructions – 

Simply fill and seal your plastic Zip lock bags with water and head outside or over a sink or bath (trust me when this experiment is complete the kids will want to see the bag get empty again lol). Have the children gently stab each pencil through the bag until it pierces both sides…and surprise, surprise, NO water leaks out!

This is such a neat activity! Our kids spent ages trying to see who could insert the highest number of pencils into the bag.

Then the inevitable happened…they wanted to pull them all out and watch the water filter out through all the holes!

We found this great idea on the Steve Spangler Science Website – he goes into great detail about how and why this works…I highly recommend checking his post here…you might also find some other cool experiments while you’re there :).
