While showing Shae The Princess Bride for the first time this week, the three of us (kids) got into a discussion about what quicksand is and how it works after watching the scene when Buttercup sinks into the lightning sand. With the Netflix theme for this month being all about staying engaged during the summer, Shae and I decided to do a little experiment.
The next morning we set out to discover the science behind quicksand. I gathered the necessary supplies; cornstarch, water, a large bowl, some food coloring for extra fun and an array of victims.
We decided to move outside because this is a notoriously messy experiment. Shae helped me pour the two main ingredients into the larger bowl but we quickly realized that there wasn’t nearly enough quicksand for a good experiment. What started out as a carefully measured experiment soon became me dumping a ton of cornstarch into a bowl and adding water in a splash at a time until we decided it was perfect. Adding the food coloring was a lot more difficult than I thought because the goo was so thick. I suggest that you add it to the water before you pour it in to guarantee even mixing.
Then we began subjecting our victims to the quicksand. First we killed the dinosaurs, then we sent a diver in to save them. We galloped some horses across the surface and then watched them slowly sink like that scene in A Neverending Story. I had Shae punch the surface and feel how oddly solid it was. We rolled the goo into balls and then watched them melt on the table.
I’m not entirely sure if Shae learned anything but it sure was a lot of fun. Cleaning up was a pain because Shae was covered up to her elbows in caked cornstarch.
