Mobile Puzzles

You can construct a mobile here. You have 3 types of tools, which you can drag to the reddish hotspots on the mobile. The hotspots only appear when you are dragging.

  • Weights: Drag these to any empty spot to insert a weight. Drag to an existing weight to replace it.
  • Crossbar: Drag a crossbar onto a hotspot to start a new balance at that point. There are three crossbar tools:
    • Replaces everything below with a fresh balance.
    • Inserts a balance and places everything below on the left branch.
    • Inserts a balance and places everything below on the right branch.
  • Scissors: Can delete a portion of the mobile. Scissors can cut strings to remove everything below, or they can cut weights to remove just that weight.

This project is made possible by a Small Business Innovation Research (SBIR) Grant from the National Science Foundation (NSF).
