I built this for my daughter, who’s an 8th grade science teacher.

Not high grade cabinetry, not even close, but the box is made of wood… basic pine boards, stained with Minwax Polyshades combo stain/varnish (I hate that stuff, dunno why I keep using it, except that it’s quick). It doesn’t show well in the picture, but the box corners were done with double rabbetted joints cut on my radial arm saw, the first time I’ve tried that… I think it came out pretty good. Of course the first attempt with warped boards went into the firestarter box! Then Titebond II and 18ga wire brads to hold it all together, final assembly with brass screws.

The classic mad scientist prop, she should have fun running it on the first day of school with a new crop of students, or on parent-teacher conference days…
