Aluminum foil as glassware scrubber: To get baked-on food off a glass pan or an oven rack, use dishwashing liquid and a ballof foil in place of a steel-wool soap pad, says Mary Findley, president of the cleaning-products developer Mary Moppins.
Heighway Pinball's solution is to introduce inductive switch technology: solid state sensors beneath the playfield, well out of the way of flying steel balls, which are triggered when a ball passes by without any physical contact.
Thousands of genes stick to each ball, and the combination is loaded into a "gene gun, " which consists of two small stainless steel chambers and a vacuum pump.
