Have you ever wondered how to make your drawings float? And by that, we don’t mean floating a few little drawings your kids made on a piece of paper in a bath. This experiment is about using science to do something peculiar and amusing. Oh, and it is easy too – it only takes 5 minutes!
What you need
How to make it
Draw something on the plate with a dry-erase marker
Pour some water on the plate
Wait a little bit and carefully move around the plate
You’ll see that the drawing literally detaches from the plate and starts to float and move on the surface of the water!
Why it happens
First of all, as you know there are different types of markers available. Most common are permanent and dry-erase. This experiment only works with a dry-erase marker. That is because it has two very important qualities. The first one is that the ink it uses has minimal adhesive and the second one is that it is insoluble (it can’t be dissolved in the water). When you pour water on the plate, it dissolves the adhesive and “tears off” your drawing but it the ink itself does not dissolve. This causes your drawing to float!
Feathers in exchange for prizes
While working on this playdate idea, our Keedoo Parrot has lost two feathers 😔 Please help us! Collect them by bringing this idea to life with your kids, and we will gratefully exchange them for valuable prizes.
