In each experiment each Macroton begins inside a blue or green Injector Tube.  In order to release the energy of the Macrotons, you must make sure each Macroton reaches a Reactor Tube of the same color.  If a Macroton escapes from the confines of the machine, it will explode, so be careful!  Does that make sense?  If not, read it again.  This is very important!

You complete each experiment by placing tubes from the Tube Tray into the machine to guide the unstable Macrotons from the Injector Tubes to the Reactor Tubes.  Often there is more than one Reactor Tube that a Macroton could activate.  It is up to you to figure out the best solution to the experiment! Remember, though - all Macrotons must reach a Reactor Tube of the same color for the experiment to complete successfully.
