These are the perfect size for my daughter's first real experiments, and I love that the rack keeps everything from rolling off the table. The calibration marks are a nice touch for teaching her to measure precise amounts.

My son loves organizing the colored lids on the rack—it makes him feel like a real scientist. The calibration marks are a great help for measuring small amounts during our kitchen experiments.
