Compasses

Pile of many, many small magnetic compasses.
Red might be north.

‘Tis the season for toy kits once more, full of little odds and ends to explore the basic principles of physics. Among them, the humble magnetic compass.

Works with the Earth’s magnetic field, permanent magnets (included in the kit), and even a homemade electromagnet (included in the kit, some assembly required).

Adorably tiny and not ideal for navigation. Please don’t entrust your wilderness survival to these.

Department Mascot

Always in season.

The drinking bird, our unofficial department mascot. Even when one takes a tumble – and when it comes to glass bird versus floor, the floor always wins – there’s a great deal of respect for our top-hatted friends.

Wanted!

Kind of surprised someone hasn’t made up T-shirts yet, to be honest.

Welcome back, spring semester!

Clouds of Dust

Plastic sheeting helps reduce the mess. Somewhat.

Ah, the annual astronomy craters lab. Lots of sand, lots of color powder, a handful of marbles and ball bearings and slingshots. And a mess that’s really something to behold.

It’s definitely a “don’t wear your good clothes” sort of lab session.

And an “all hands on deck” cleanup effort.
