Trail Snacks

Physics doesn’t rely on field work as much as some other disciplines – biology, geology – but sometimes it’s necessary and the fresh air does us good. So do the occasional wild treats found along the trail.

Just be sure to share them with the local bears and birds!

Good ol’ Penn Roosevelt dam!

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!

Silicone Sealant

“and many plastics”

Because sometimes you need to seal up a joint, and the materials that can do the job don’t play well with adhesives. When working with Delrin, you’re thankful for the excellent machinability, less so for how much of a struggle it is to get anything to stick to it. Could be worse, right? Could be PTFE (Teflon).

Even this silicone sealant is a “sort-of” solution, and it sticks to everything. Always threatens to make a real mess of things. But it’s reliable for waterproofing and can take a variety of abuses from heat to chemicals. And it comes on a “job-size package.”

Having just gone through about a dozen of these things on a single job, we may take some issue with that descriptor. And the rather optimistic 10-20 minutes to being tack-free. But it’s still impressive and effective stuff.

And compared to some other goop around here, doesn’t stink to high heaven.
