All you need is something to 'hold' a drip of water - I pipette or syringe is best but it can be done with a chopstick, a laser (any colour) and a white wall or screen tk project the image on.
Suspend the drip, shine the laser through the drip and see the amazing tiny things living in the water.
I've not done it for a while, I better try this out again soon, the kids will love it.

Pond water is perfect for using in a DIY laser microscope https://civilpedia.org/p/?t=Laser-Microscope&pid=30
