Customer Reviews

Perfect for demonstrations! Review by karen engates

I couldn't wait to get this item in my hands for my science camps. I spent many years lugging around an aquarium for demonstrations, and this is a more lightweight, clearer, and compact piece of equipment that satisfies every requirement in my book. And it doesn't use as much water as an old aquarium either! I've used it to demonstrate density (sink/float of candies, sodas), buoyancy, light refraction, suspensions, and even filled it with soil materials to demonstrate aquifers and other geologic events. This is worth the money for every educator to have on their science shelf of goodies. (Posted on 5/17/13)
