Slow-Motion Video: We Slice Through Bottles and Cans

Remember when master knifemaker Bob Kramer came to the PopSci office just to slice our soda cans in half? Great fun! But how we wished we had had an ultra-slow-motion camera like the Phantom on hand that day.

We couldn’t just let it go. So, armed with our own Kramer knife and our Phantom, we attempted to replicate the feat. It took a little practice, a lot of sharpening, and a pretty high knife-tip velocity, but here’s the slow-mo video for your edification!

I recommend watching it full-screen.

And here — just to refresh your memory — is the master at work.
