The BBC have recently launched a new science programme, its kind of a cross between Top Gear and Tomorrows World (for those who remember that…).  Each week they do some cool experiments and generally get to play with science.
A few weeks ago they made a huge vortex cannon to knock over some objects, just because they could. Â This kind of program I love so I had to post it for all the science loving geeks too
