Way cool science you can really use: How to prevent a shaken soda can from exploding.

I'm sure we've all experienced the indignity of having a soda can explode all over us at one point or another in our lives. I was always taught to flick the top of the can a few times to prevent this. Turns out, that doesn't even work.

This vid shows the proper way to prevent an explosion and explains the science behind the phenomenon.



Science can be cool, fun and it can save your wardrobe.

Flicking the top does the same thing. The shock waves are enough to release the bubbles which had accumulated.

I guess it could work eventually. The way they show it, flicking it directly from the sides seems much more eficient and would probably take less time and wear or your fingertips.

This is nifty and useful.

Thanks for sharing

I suppose, but tapping a closed receptacle literally anywhere will send waves through it. As long as the can is standing upright, gravity/air density will do the rest.

Thats pretty cool.....cheers for that.

Must find my safety glasses though for when i next drink a can.

CX.

YeeHaa! No more wasted Beer because someone wanted a chuckle.

Gotta admit though, I've shaked up a couple myself at picnics and given them to others. But they usually deserve it as they have done the same to me.

Yep, I have a sad sense of humor...sue me. But now you have given me a leg up on the competition.
