What can you do with a laser at home? Tease a cat, of course, but can you use it to measure something really small?
Supplies needed to participate in all the activities:
● Inexpensive laser pointer
● A hair, preferably from someone with dark hair. Gray hair doesn’t really work, although blonde seems to. The hair needs to be a few cm long. You could also use fine thread.
● Calculator or calculator app
