My third graders were able to directly verify that two different-looking shapes can hold the same amount of water, which made the volume concept click instantly. The stopper seals tightly enough for sand as well as liquid.

The removable base makes filling these with water or sand so simple, no more messy spills during our homeschool math lessons. My kids can finally see how volume compares between different shapes, and the stopper seals tight enough for quick experiments. Definitely worth it for hands-on learners.

My third graders love using these with rice to see which shape holds more. The removable base makes it so easy to fill and empty without a mess. Really solid for classroom use.
