The jetpacks still aren't here, but now we can at least have DigitalDawn curtains. Ooooh! Ahhhh! And we can also travel by being strapped to a helium balloon, sort of! (I wish I'd seen this earlier; I would have gone up to Columbus to try it out on the demonstration day.)

Scientists need volunteers to help them measure oxygen deficiency effects, and they're going to conduct the experiments at the base camp of Mt. Everest. If, like me, you're fascinated by the Himalayas but will probably never be a skilled mountain climber, this is one way to see them.

Meanwhile, down here around sea level, there are pink grapefruit-flavored Mentos (in Canada) and experiments with making gigantic candy via Pimp That Snack. (The Twix of Terror and the Pimpermint Patty are two recent notable results.)
