We all know Isaac Newton discovered gravity because an apple fell on his head. But, what most people don't know, is that he couldn't have done it without you. If you don't put up obstacles along the way, the apple might have never fallen on his head. Help him discover gravity by making sure the apple does hit him. Do it for science, do it for us!
Choose the eraser or the pencil with your mouse and draw. Use the space bar to drop the apples.
