Preview of Leeuwenhoek ball-lens microscope
By Krypto
Complexity
Simple
MAIN PURPOSE: See cells with a single glass bead lens
A slide-sized plate with seats for a 2 mm and a 3 mm glass bead, the trick Antonie van Leeuwenhoek used in the 1670s: tape a specimen to the back, hold the bead to your eye and see cells at up to 150 times, with a lens that cost almost nothing.

Preview of Eureka overflow can for rock density
By Krypto
Complexity
Simple
MAIN PURPOSE: Measure rock volume and density by displacement
Fill the can until water runs from the spout, lower in a rock on a thread and catch the overflow in a measuring cylinder: that is the rock volume. Divide its weight by it and pupils can tell granite from basalt from a lump of pyrite by density alone.
