Science of toys

This is an updated production of a program originally broadcast two years earlier, entitled "Science of toys." Lynn Poole points out that over 1,400 different toys are now manufactured for learning and sportsmanship. He visits a studio toy shop with local child Joey Vitale where "shopkeeper" John Lockwood explains the science of such toys as slinky pull trains, punching bags, gear toys, a helicopter launcher, an electric airplane and steam engine, wind-up toys, and cog-driven toys. The trio also looks at how flexible plastics are now used to make some toys safer and dolls softer. They consider polarization in magnets, static electricity in balloons, ball bearings in bike wheels, and how toys were invented. Kits on the shelf include a chemistry set, a super sleuth science kit, and a weatherman set.
