Heatproof, transparent, and durable, the mason jar is a science lab just waiting to be discovered. Unlock its potential with 40 dynamic experiments for budding scientists ages 8 and up. Using just a jar and a few ordinary household items, children learn to create miniature clouds, tiny tornadoes, small stalactites, and, of course, great goo and super slime! With a little ingenuity, the jar can be converted into a lava lamp, a water prism, a balloon barometer, and a compass. Each fun-packed project offers small-scale ways to illustrate the big-picture principles of chemistry, botany, biology, physics, and more.
