A hockey puck can go fast on ice because of a lack of resistance, but what about on other surfaces?

“My hypothesis was if a surface is flat, smooth and hard like ice is, then the puck should slide on that surface like it does on ice,” said a local student who did a science project on overcoming resistance.

The student got a bunch of different surfaces, like cardboard and a mirror, to test the hypothesis. Check it out in the “Science Break” segment above.
