Have some wine corks hanging around the house? Maybe not enough to make a bulletin board or even a coaster?
Here's how we use the ones languishing in our house:
Re-purpose Number 137: Door Stop.
(I like prime numbers. Speaking of primes, I picked this one out of thin air, but apparently, it's a nice solid strong, Chen, Stern and Eisenstein prime. Geek-out done.)
Re-purpose Number 139: Dimmer Switch
(Random mathematical fact - 139 is the twin prime of 137)
Lazy or resourceful? You decide.
