Product Description
Award-winning video and lesson investigations on the topic of surface tension. Key concepts include:
- Water behaves as though it has a ‘skin’ on its surface.
- When separate streams of water flow, each has its own surface ‘skin’.
- If these streams are made to touch each other, their surfaces join up to make one combined surface.
- This ‘skin-like’ quality at the water’s surface is called ‘surface tension’.
- Surface tension makes water cling to itself.
- When streams of water come into contact with each other they combine to give the smallest overall surface.
- Disturbing the combined stream can recreate the separate streams.
