Floating Drawings |Dry Erase Markers Science Experiments| Easy Kids Experiments | Science Activities
If you love easy setup and minimum material activities this one is just perfect! Also this will let kids go wow watching hearts floating around.
All you need:
White Board Marker
Plate Or Tray ceramic \ glass
Water
Straw(Optional)
Draw hearts or any other figure ,letter or shape it must be thick..with board marker add some water and blow softly ..the hearts will start floating. You have to try again and again to observe this science experiment.
According to Mould, the ink in dry erase markers is also insoluble. That means it can’t be dissolved in a liquid, and more importantly, it means it’s less dense than water. When you pour water onto a dry erase stick figure doodled on a smooth surface, a strong buoyancy force overcomes the stickiness of the ink, pulling the doodle off the surface and causing it to not-so-magically float on the water.
Does knowing how this trick works make it seem any less amazing? Thankfully not. And there’s no reason you have to show this explainer to your friends before you make a doodle magically float away.
