Kids Science Lab Kit — 50+ Chemistry Experiments for Young Scientists

Our building block set is designed for ages 18 months to 5 years. The blocks are large enough to be safe for toddlers (no choking hazards) and the activity cards span beginner to advanced challenges that grow with your child.

All blocks are made from 100% BPA-free, food-grade silicone. They meet or exceed ASTM F963, CPSIA, and EN71 safety standards. Every batch is independently lab-tested. They're soft enough for teething but sturdy enough for ambitious towers.

Each Starter Set includes 50 blocks in 12 shapes, 10 double-sided activity cards, and a reusable canvas storage tote. The Family and Mega bundles include 3 or 5 complete sets respectively — great for bigger builds or multiple kids.

Yes! Silicone blocks are dishwasher-safe (top rack) and can also be wiped down with soap and water. The activity cards are laminated and wipe-clean. The canvas tote is machine-washable.

Unlike hard plastic blocks, our silicone blocks are soft, quiet, and grip-friendly for little hands. They don't hurt when stepped on (parents, you're welcome). Plus the educator-designed activity card system gives you a clear progression path — it's not just blocks, it's a developmental tool.

We offer a 30-Day Happiness Guarantee. If your little one doesn't love it, send it back for a full refund — no questions asked. We're parents too, and we only sell toys we'd give our own kids.
