Kosmos's science calendar for 2026: 24 small boxes, each a new experiment from chemistry, physics and beyond, light guides, stair-hoppers, illusions and UV beads among them, each doable in a few minutes before school, with a note on the science behind the effect. Eight and up.
Kosmos gives the format and a few examples and keeps the 24 experiments for the doors. The experiments are new for this edition, the maker says; the calendar has run for years.

The German science calendar, and still the one to buy for an eight-year-old who asks why: twenty-four experiments that work in minutes and explain themselves. Four stars.
