As a follow-up on the computer parts story below, Alex had the idea of making a little fan for himself. He thought he’d set it on his desk so when he’s working at the desk and gets hot, he could turn it on and cool down a bit. (A very little bit, as it turns out, because these fans don’t push that much air.)
So I helped him rip out the appropriate parts from the computer, plug it into a 9-volt battery, and voila! He did almost all of the work, minus some soldering that proved a bit problematic.
Now Zack and Kyra want their own fans, and there was talk of installing one on the outside of the rats’ cage to keep them cool on hot summer afternoons. Heh.
