|This is an April Fools' Day version of Simulating Gravity. Please don't take it seriously. You can find the original here.|
1. Go to the highest floor in your house. Find a room with a window.
2. Open the window.
3. Grab your laptop (with Scratch currently running on it) and drop it out your window.
You just simulated gravity! Gravity is the force that pulled your book down. If you really like math, you can go get the laptop, but you might be better off without it.
