I'm sure everyone reading this knows what a sniper rifle is. You know: long barrel, cylindrical scope, big long bullets, used for long range and heavily armored targets. But, what you might not know is how powerful one is. The standard NATO sniper rifle bullet is the .5 BMG. Made in 1921, the most powerful version of that cartridge is about .052 kg, and leaves the rifle at 882 m/s. p = mv, so p = (.052)(882) = 45.86 Ns. That big fat hunk of copper has about 50 Ns of life in it. Now, the average adult human head weighs about 4.5  5 kg. Seen as how I'm writing this I'll use myself as the test s

Wearing a helmet is all about impulse, change in momentum and the force of impact. This video illustrates why you should secure your helmet to your head. Thank you very much to Colton and Jean Johnson who said yes when I asked them if I could film myself riding my bike off their dock. Colton also said, â€œIn my 75 years of living, that has got to be the strangest request I have ever received.â€ Thank you also to Chris Palmer and Larry Braak for being my onsite camera operators.

When cars get into a collision, why does it seem like half the car gets turned into debris? The answer is simple, conservation of momentum. In elastic collisions, like car crashes, the projectiles have a lot of momentum. If a head on collision occurred where the cars stayed perfectly rigid, the occupants would have a huge change in momentum. This used to happen before modern safety regulations. Modern cars are designed to "give", absorbing a large amount of momentum and keeping the occupants from experiencing the same change in momentum, saving lives and livelihoods in the process. It

These beads seem to levitate, defy gravity and jump out of the beaker. But how and why do they act like this? We met up with Steve Mould, the science guy from Britain's Brightest, to explore the science behind the "self siphoning beads"  also known as "Newton's Beads". To get a closer look at the phenomenon, we filmed them in slow motion to try to work out what exactly was happening, and how the behaviour changes with height.
