This project is better in TurboWarp with Infinite Clones on: https://experiments.turbowarp.org/interpolation/484324607?clones=Infinity Click the green flag. Hold [S] to show settings variables. Press [space] to start the reaction. Some of the settings will disappear once the reaction is started. The Spacing variable changes how close the Uranium atoms are (only available in TurboWarp with Infinite Clones) The Particles variable changes how many neutrons shoot off the Uranium atoms. The Rods variable puts rods that absorb the neutrons in between the Uranium atoms. I got the idea for this project after a science lesson. :)
