Welcome to the Atom Builder version 1.31

General Instructions:

Drag objects onto the atom, or off of it, or build a new atom from scratch. You can drag electrons back into the bin. Some combinations of particles are possible and other combinations are not possible, just like in nature.

You can Test your atom using the > button. When you get into the testing world, drive around (using the arrow keys) and see what happens. Watch out for the glows!

The Gnome is safety minded and keeps your atom out of a certain kind of trouble. But you can live dangerously. Ask Andy Johnson how to test atoms that the Gnome doesn't want you to test, and how to activate the clock feature.
