‘Baffling’ balloon experiment explained by best dad ever
Why does the balloon move forward when the van accelerates [forward], while the plumb bob swings backward?

Starring an Inanimate Carbon Rod!
Magnetically actuated micro-robots for advanced manipulation applications.
In rod we trust.
Induction in the Hole!
Another video of the Navy’s railgun (I did an analysis of an earlier test a few years back), which is slated to be tested at sea pretty soon.
How Do You Make an Aluminum Float?
Here’s a couple of videos I ran across involving magnetic levitation. You have a changing magnetic field, which induces a current in a conductor, making a field that gives you a net repulsion.
So what happens if you let the levitating material continue to heat up? This second video starts a little slow, but be patient. It’s fun at the end.
Absolutely
Great job distilling the concepts here — that not everything is relative. It’s just that there are things like length and time (and related concepts like simultaneity) that we once thought we absolute, and it’s hard to wrap one’s head around the fact that they depend on your frame of reference.
And the Number of the Counting Shall be Three
Another great Veritasium video. I got to meek Derek at ScienceOnline this past week, and we were in the same dinner group one night but ended up at opposite ends of the table, so I didn’t get to chat as much as I would have liked.
The video shows a great example of how scientists have to not trick themselves by only doing tests that would confirm the mechanism of their hypothesis. You have to see if some other mechanism would work as well.
When You Can't Duck and Cover, Ride it Out
The whole video is fun, but there’s a very neat bit at the end
It Sounds Uplifting to Me
Die, Frosty. Die!
These days, when my brother and I get together, things blow up and/or projectiles move through the air. There was wet snow on the ground, so me made a snowman. And then dismantled it, some of which I filmed in slow-motion (420 fps)
If anyone asks, we were in Pennsylvania.
