While washing dishes a few days ago, I accidentally got a smaller glass stuck inside a slightly larger glass. I knew that heat or cold would make them expand or contract and could potentially solve my problem but I can never remember which does what and have a fear of broken glass... So I left them on the counter for the hubs to find and fix... eventually.
Tonight, the hubs simply placed the large glass in a pot of hot water and filled the smaller glass with ice.
Me: Wow. Neat. Did you google that?
Hubs: No. It's just physics.
"It's just physics."
