Let's Experiment with Energy |
| A lump of coal is a form of energy, but what exactly is energy? Eight delightful experiments teach us about energy and make us use our bodies and brains. Educational and fun, too! |
| Let's spin disks using the energy of light! |
| Watch the disks that spin when a light is shined on them. Actually, the reason they spin is because the hidden solar battery changes 'something' into 'something'!?! |
