If you love our science activities as much as we do, you will find plenty more simple and budget-friendly science ideas below that pack a learning punch.

Now of course when you remove the pencils the holes will be left and the water will definitely leak out, everywhere. See what happens when you try to push a dull or unsharpened pencil through! The chains or strands are pushed aside by the pointy pencil but then re-seal themselves around the pencil preventing water from leaking out.
When the sharpened pencil pushes through the plastic bag, it’s actually pushing through the polymer chains. The plastic bag is made up of polymers which are long strands or chains of molecules. This leakproof pencil bag science experiment may look a lot like magic, but it’s also cool chemistry! What’s going on between the water, the plastic bag, and the sharpened pencils.

Looking for easy science process information and free journal page?Ĭlick below to get your quick and easy science activities. Of course, your neighbors might think you are a little mad when you go to set this science experiment up! What might you experiment with in chemistry? Classically we think of a mad scientist and lots of bubbling beakers, and yes there are reactions between common acids and bases to enjoy! Also, chemistry involves matter, changes, solutions, and the list goes on and on.
Chemistry is a base for physics, so you will see overlap! It’s also how these materials act under different conditions and go through changes. That’s what our leakproof pencil bag science activity is going to show us! Let’s keep it basic for our younger or junior scientists! Chemistry is all about the way different materials are put together, and how they are made up including atoms and molecules. Or how about another phrase: you know where you poke a bunch of pencils into a bag of water and nothing leaks out? So I am calling it my leakproof pencil bag science activity! A little clumsy but you get the idea! How do you even go about describing what you are looking for to google? Magical water bag and pencil science trick thingy? Did we? MAGICAL LEAKPROOF PENCIL BAG SCIENCE EXPERIMENT! Sometimes science can appear a bit magical don’t you think! I bet you have seen this leakproof pencil bag science experiment trick before but we love to try cool science and STEM here too! So we set up the leakproof pencil bag science experiment to see if we could actually pull it off without getting soaked.
