Turn the countdown to a holiday, birthday or special event into a daily science celebration with the 12 Days of Science Experiments Countdown Calendar. This kit from MindWare includes 12 numbered test-tube experiments—each day uncovers a new mini-lab complete with materials and instructions.

Experiments include surprising reactions like water-disappearing, instant snow and underwater eruptions, introducing young learners to chemistry and physics concepts in a safe, playful way.

Because each experiment is compact, self-contained, and reusable (minus common household items like water or salt), it’s ideal for classroom use, sibling sharing, or a family tradition of discovery. Aside from the fun surprises, children practise observation, prediction, inference and reflection—skills key to STEM learning.

Recommended for ages 6 and up, the set supports a sense of wonder, builds fine-motor and cognitive skills, and turns “waiting for the big day” into meaningful hands-on science time. With 12 days of discovery, you get both countdown fun and educational depth.
