MindWare 12 Days of Science Advent Calendar, 12 Test-Tube Experiments
✓ Product data checked October 29, 2026
MindWare swaps the usual 24 doors for 12 test tubes in a holder: each tube holds the ingredients and step-by-step instructions for one experiment, such as disappearing water, an underwater volcano or instant snow. MindWare marks it ages 6+, and an older child can run most experiments alone. Because it only has 12 days, you can start it on December 13 or use it to count down to a birthday. It is rated 4.5 across 142 reviews on Amazon US, at about $26.
Why it makes a good gift
Best for : A curious child of 6 to 10 who likes to mix, measure and watch something fizz or change.
Best occasion : The last 12 days before Christmas, or a birthday countdown.
Why it works : Each tube is a small hands-on project with a visible result, so the countdown becomes a daily kitchen-table experiment rather than a treat, and the test-tube holder makes the box feel like real lab kit.
Avoid if : You want a full 24-day calendar, or the child has already done the classic baking-soda experiments many times.
