Must-see videos of the week: March 9-15

This week, we saw videos that encourage you to play with your food, take up a new sport, groove when the music speaks to you, and always have that camera ready because you never know what wild thing you'll see out in this crazy world of ours. So grab your chopsticks, tune up that guitar and check out our must-see videos of the week.

In the 'science is awesome!' category this week, we see the main course in a restaurant become animated with the help of a little chemical reaction. When the squid in this dish, known as Odori Don, has soy sauce poured on it, it reacts to the sodium chloride (salt). NPR explains that even though the head (and therefore brain) has been removed from the creature, the salt acts as a replacement for the electrical signals that would normally be sent from the brain, telling them to relax or contract. Still, looks pretty freaky!

Twin sisters Shelby and Monica Church are the kind of people you can't help but be impressed by (and a little jealous of). The twin sisters are gymnasts, divers, and YouTube stars, with a real flair for film-making if this slow-motion gymnastics video is any indication. The girls capture some of their fellow high-level gymnasts showing off their skills, with the footage slowed down so you can appreciate all the effort and skill required for the sport.

If I've said it once, I'll say it a thousand times: Do not try this at home, kids. Dominik Sky is a adrenaline junkie who has YouTube videos featuring him doing parkour and free-running in some truly crazy places. This video from November, which is gaining new popularity now, shows him making a terrifying leap from the top of a seven-metre (23-foot) tower.

A pilot and skydiver narrowly avoided serious injury earlier this week when the plane became entangled in the strings of the skydiver's parachute. Sharon Trembley, 87, was doing takeoff and landing maneuvers at a local airport in his Cessna, while skydiver John S. Frost was descending, CBS News reports. A photographer managed to capture the whole incident on his camera.

And finally, everyone's favourite Canadian rock star astronaut gave another musical performance this week (this one was on terra firma, though). At an event in Dublin, Ireland, Chris Hadfield took the guitar of fan and attendee Paul McNeive, and performed this moving rendition of Danny Boy. Just in time for St. Patrick's Day on Monday!
