Building a Stonehenge – without the Woo.

We’re out at a trade show today so today’s entry will be a bit brief: Many folks have come up with ideas as to how ancient Briton’s moved the heavy stones that make up Stonehenge. Some of the theories make sense, but many of them are a wee tad…speculative, to be kind. Aliens, psychic powers, [...]

Zero Blasters and Vortex Rings

Such toys have actually been made for ages  (usually home-made versions, although Wham-O make an air blaster for a while) [...]
