Martin Gardner's 'Science Magic: Tricks and Puzzles' teaches fun and easy experiments to demonstrate physics. I'm thrilled with the new tricks I'm learning!
Gardner shares exciting, and generally simple, science experiments with engaging, sometimes astounding results. Play with the adhesion and cohesion of water, magnetism, volume and mass, friction, stiction, pressure, and tons of other fascinating scientific properties, to both learn and amaze.
Some simple effects, like 'three jets' are pretty simple, where you drill holes in a milk carton at different levels to show changes in water pressure, however some are not for younger kids to try on their own. 'The electric pickle' is one that requires adult supervision. A glowing pickle is certainly cool, but spiking a cucumber, and plugging it into a wall socket via a cut extension cord, is something I'd prefer an adult be present for.
My kid and I are having fun playing with 1-2 of these experiments each week. A few of the presentations may become magic tricks I use with friends.
