Comments about Arbor Scientific Inertia Apparatus:
Easy to set up and use. I added some red tape to the edges of the plexi-glass plate to make it easier for the students further back to see.

It is completely safe but it is better to be aware it because the metal could be damaged due to the excess of usage. Anyway, great value and very easy to use
