Day 56: Candy Wave Machine
Astronomy: We’re currently learning about light and the electromagnetic spectrum. Which is why this tweet from Alom Shaha over the Thanksgiving weekend couldn’t have been more perfectly timed:
So on Sunday, I got a pack of 75 kebab skewers, 3 boxes of Dots candy (~150 Dots), and some tape:
And today I had the students assemble our own wave machine:
The skewers were spaced 10 cm apart and the whole machine spanned almost 24 feet. Here it is in action:
- Use duct tape. The tape needs to be under A LOT of tension. Weaker tape will just rip.
- Buy an extra box of candy. We would’ve had about 5-10 more sticks if kids didn’t sneak a few candies to eat.
- Put an extra layer of tape over the duct tape. (Non-duct tape is fine.) It keeps the skewers from sliding off at large amplitudes.
