Down arrow= change size bigger Up arrow= change size smaller You can control the rainbow with your mouse but if you move too fast with the mouse, the rainbow won't stick together. BTW: when you press the down arrow, it makes the size bigger and when you press the up button, it makes the size smaller! Enjoy!
I want to give thanks to Pearlstar. I got the idea from that user. When I saw what she did, I tried to do that too but I changed some things up a bit.
