November 20, 2018: Laser Spiders

Old and busted: Everybody's played with cats and laser pointers. The new hotness (??): I have read reports online that jumping spiders (!!) can also see laser dots . . . red works, green is better . . . and will try to chase them. I have plenty of jumping spiders around here, but alas, no laser pointer. So if you have both, please try it out for me and let me know in the comments! (Crowdsourced geeky info for the win.)
