Easy Experiment: Stab a potato with a straw

Posted December 23, 2014

I wrote about Beth Harris last week. She's the Raleigh mom of two and creator of Fort Kits for Kids. I know Go Ask Mom readers have been keeping her busy with holiday orders since that post!

In addition to making the Fort Kits, Harris also is a long-time science educator. I thought it would be fun for her to share a few easy experiments that families can do at home with things that you probably have around the house. 

We'll start today with this one which requires only a potato and a plastic straw. Watch the video to see how it's done. It's a fun way to learn all about air pressure. Harris' website has more science activities.

    I just LOVE Science and especially engineering – the practical side of Science. I’m an ‘older’ engineer that has, for the last decade or so, has slowly transformed myself into a Scientist….

    So, onward to the point: “What have we learned from this ‘experiment’? Answer: ‘Flimsy’ things may not be so flimsy if the time is short enough. What have we learned that is practical?

    If you want to drive a staple through a very thick stack of paper, first gently push down on the driver until the staple breaks free of the stack. Then hit the driver very hard. The speed of the blow will drive the staple through the paper without bending (usually) when a slower push would have bent it….

    Ain’t Science fun??
