200 balls, one hair apart, dropped from the exact centre, from rest. The butterfly effect: each bounce multiplies the difference by seven. Deterministic and completely unpredictable. Nothing here is random: identical balls, identical physics. 0.1 mm of doubt was all it took.
Check out this magnet setup. You see that? Before I show you what this is used for, let me show you how it works. Each of these silver spots is a permanent magnet slipped into this plastic ring. When I bring another magnet close, you'll see it's attracted to each of these. They're all oriented the same way. I'm going to flip it over. So now you can
As your fist hits the bag, it sends a bar swinging inside, pushing a blade through a beam of light. But this blade has a slit in it, which briefly lets the light through as it passes. It measures how long it shined through the slit and calculates that into your score. So to hack it, call up Bork, your obese T-Rex. 0.09 Seconds 0.82 Seconds 470 713
What happens if you fire a gun underwater? Short answer: nothing good. But the physics is interesting. Let's break it down. First, a bullet doesn't actually need oxygen to fire. The gunpowder contains its own oxidizer. That's why guns can fire in space. Wait, so I can shoot in space? Theoretically, but there are three big problems underwater. One,
I noticed this is pi each time. The video shows a simulation of elastic collisions between two blocks and a wall. The left block has a mass of 1 kg. The right block's mass increases from 1 kg to 100 kg, then 10,000 kg, 1,000,000 kg, and finally 100,000,000 kg. The number of collisions is counted and displayed. As the mass of the right block increas
What happens if you shake a magnet like crazy over an iron plate? Something incredible happens. The atoms inside the iron plate get violently agitated by the magnetic field. The friction from this makes the plate heat up. So what if you shake a magnet over a pot? The pot heats up too. Hey, you could actually cook with that! But you can't stand ther
