Boxes Upon Boxes

The Original.

In great big boxes full of boxes, the toys begin to arrive. We stash them in corners, in front of other shelves, any place mostly out of the way before separating, sorting, packing, and distributing.

Three hundred yo-yos, Imperials and Butterflies, in an assortment of colors. Every box is full of surprises!

Slide Projector

Slide projector, no carousel
The classic.

Remember slide film? Carousels and projectors and hauling out the big screen to see those vacation photos? Are you old enough to remember high school and/or college lectures on slides? The shop techs remember.

Nowadays everyone’s much more likely to use Slides than slides, of course. More portable, for the most part. Easier to edit, up until the last moment. Overall, a lot of advantages. But the old-school ones were pretty cool, too.

One can only hope that back in the days of the Audio-Visual Aids Department (we’re assuming they’ve been subsumed into L&IT, but not ruling out the possibility of a now-defunct academic department), they wheeled these – and film projectors, and VCRs, and hopefully LaserDiscs, too – into your classroom space on the classic steel cart. Embedded YouTube clips just aren’t the same.

Pinholes

It’s the sun!

Much of our day revolves around the Physics and Astronomy labs in Olin Science Building, which was the finest construction the budget could shoulder in 1954.

Which, after 7 decades, some renovations, and who knows what else, means there are a few minor holes here and there.

Holes which act like a pinhole camera in an otherwise dark lab, casting images of the sun and tree branches on the floor.

Copper-coated

Shiny!

Copper-coated steel BBs, used in several different labs throughout physics and astronomy. Like many of the odds and ends we use for labs and demonstrations, these aren’t used as intended by the manufacturer. In this case, one can only imagine that off-label use is actually safer.

Stopper Knots

Kevlar string, of course.

There are a handful of occupations and/or hobbies which reward those interested in the craft of knot-tying. The big ones include boating, camping, climbing, and fishing. (There may be hobby overlap.) Arborists, equestrians, and surgeons need specific, functional knots, too.

Turns out so do lab technicians.

We’re slowly adding knots to our repertoire, for all manner of purposes. Pictured above: a doubled-up double overhand stopper. (A single knot was insufficiently stopper-ing given the thread diameter and pendulum bobs on hand.) Alpine butterflies, bowlines, non-slip mono loops, trucker’s hitches. Now we just want an excuse to use the Double Dragon Loop!

Colorful Prizes

A small selection of bright, bright colors.

Thanksgiving break is nearly upon us, and the student body is desperate to extend their week-long break into something even longer. But classes are still in session! There are still amazing and exciting things to learn!

And we have toys to give away!

Annual tradition to encourage our introductory physics to stick around: problem session prizes. Puzzle games, fidget spinners, stretchy rubber toys, and some other unidentifiable plastic oddities that came in the variety packs. It’s a literal grab-bag of eye-searingly bright toys.

Have a happy Thanksgiving break!

Doppler Ball

Orange foam ball on cable
The noise is more obnoxious than the color.

An electronic buzzer buried inside a foam ball, on a long cable with a switch and handle at the end. Flick the switch, and a piercing 2,500 Hz signal begins. Whirled in a big circle around your own head, the tone persists. For everyone else in the room, it creates a cyclic Doppler shift, a repeating weeee-oooo, weeee-oooo that sticks in the brain even after it’s done, like when you see phosphene images behind your eyelids after catching a glimpse of something way too bright.

We can’t overstate the wonderful modifications to the original object, back in 2010, which added the cable and switch. Your bog-standard Doppler ball – available from several scientific apparatus purveyors – requires one to open up the ball, turn on the buzzer, then close it back up. Tossing it back and forth between students illustrates the concept.

Then, when you’ve had quite enough and just want it to stop, you have to pry it open and shut the whole thing off. (This vintage version, pre-mod, required full-on battery removal.) The Doppler ball: it teaches us all kinds of new lessons!
