Here’s a quick STEM experiment that will technically teach your kids about centrifugal force (i.e. the same technology used in commercial water pumps, such as a laundry machine when it’s draining). But even the science is too advanced for your child, there’s the pure fun of spraying water!
To put together the “fountain”, cut a straw to about 2/3 of its length. Snip two holes at even intervals, sniping into but not through the straw, so it now has three segments.
Poke a hole in the middle of the center segment with a needle, and then insert a skewer. Fold the other two segments down toward the tip of the skewer; you now have a triangle. Tape it all in place.
Fill a glass with water and head some place where it’s okay to get wet! Our patio was perfect. To activate the fountain, just roll the skewer between your palms.
Unfortunately it was really hard to capture photos of the fountain in motion, because Travis couldn’t quite master the trick of rolling the skewer quickly enough to make the triangle spin. When I showed him how to do it, on the other hand, our fountain worked fantastic but Travis kept stepping back to avoid getting wet and didn’t take any pictures!
Still, it was well worth the effort to make this craft. The D.I.Y. “sprinkler” was just right for a warm spring morning!
