Double Bubble Trouble - Click Green Flag, Choose your Speed, then Click the Stage to begin. Pop a bubble by clicking on it. It's hard to do, unless you hold the Mouse Down and put the Mouse Pointer in the path of an oncoming bubble. Hit B (Blue) or L (Lilac) to fix a single Bubble of that colour centre-stage, showing the bubble bouncing Code working perfectly, which it can't do in its usual mode (see the Tutorial for the reasons).
Created by @gregatku for use in Coding Classes for Kids Unlimited, for whom I work as a Coding teacher. Extends ideas explored in Pong where a Ball bounces off a flat horizontal surface, where now bubbles bounce off other bubbles, with a curved surface. Uses a Local (for this sprite only) Variable so each Clone has its own copy. Contains a Tutorial explaining how the Code works (& why it sometimes doesn't).
