Everyday physics/chemistry
An interesting phenomenon:
I make tea at the office by heating my mug of water in the microwave for a couple minutes. I usually put half a packet of Splenda in the water first, and there's also tea residue left in, as I only take the mug home to wash it every few days.
The water is no longer boiling by the time I open the microwave door. But if I get there quick enough, dropping the tea bag in results in a sudden, brief flurry of bubbles. Why?
