Clever things
Not all Astro-Didaktik articles come from the pen of our founder Klaus Hünig. However, we do not want to withhold them from you - after all, they are clever things.
They include entertaining gimmicks like the little steam yacht, the Pythagorean cup or the solar airship. But you will also find useful things like the fire iron with ignition magnesium, the black or red light lamp, small compasses or round spirit levels.
