Merry Grav-Mass!

So I saw many „Merry Christmas“ posts here lately.
But many of you may have forgotten that 25th of December is the birthday of the greatest physician and mathematician of all time — Isaac Newton! So let's celebrate the existence of comprehensible physical laws!

One way to celebrate Grav-Mass is to decorate a tree with apples and other fruits. Glue them or attach them, but not too well! The idea is that occasionally a fruit should fall. Put them on the tree no more than 2 feet up, so that they won't get damaged or hurt anybody when they fall. Investigating and perfecting the methods for doing this is a great way expose a child to the process of scientifically studying the behavior of the physical world.

Merry Grav-Mass and happy New Year! 🍎
