Instructions: This is a water simulation using ball physics and the pen extension. It is very laggy in vanilla Scratch so use TurboWarp: https://turbowarp.org/1121828509?hqpen Use right and left arrow keys to swish the water left and right. Up arrow to lower gravity and make the balls float. Credits: Thanks to @Griffpatch-Academy for the walkthrough! Pen physics are always really cool! Who knew that a few months later I would be making even more pen games lol.
