Who would have ever thought that a plastic bag, some water, and a few pencils would have adults screaming with fear? Learn how to poke holes in a plastic bag filled with water without spilling a drop. Well, that’s the theory you’re going to test… and it’s wise to practice your liquid trick over the sink. It’s a cool way to learn about the chemistry of polymers. Continue reading
Did you know that you can cause a packet of ketchup to rise and fall on command in a bottle of water? People might even think that you have the ability to move objects with your mind! The truth is that you don’t have the gift of telekinesis. You actually just know a really cool science trick! Continue reading
A candle and beaker of pink phenolphthalein solution are placed inside a jar. The candle is lit and the jar is capped. The flame expectedly goes out as the oxygen is depleted. After the flame is extinguished, the pink solution slowly fades to colourless. What has happened inside the jar?

We’ve all opened a package filled with hundreds of those pesky foam peanuts. Leave it to our science guy Steve Spangler to create an unforgettable recycling lesson on the science of polystyrene. Continue reading
Show students a “special” balloon that doesn’t pop when exposed to a flame. Students will come up with very clever ideas for why the balloon doesn’t pop. But, when all is said and done, the “magic” is the result of important scientific principles involving specific heat capacity and heat transfer. Continue reading
