With luck the vortex launchers will arrive noonish today (Tues).
Come find me in the Apparatus Competition room (Farnsworth room) adjoining the main
registration room in the Student Union. I'll be there from 1pm to 6pm. Worst case if they arrive Wed. noon, I'll be in Farnsworth from 1PM -3PM taking down the exhibits.
Also come and check out hand-drawn holograms and such, PIRA display, and Apparatus Competition entries, currently on display in Farnsworth. Note that PIRA has a small "freebies" table there.
I also brought along some remaining "group purchase" material from Seattle Weird Science Salon:
Thick-wall copper tubes for Lenz Law demo (very few)
