You can train yourself to move one eye independent of the other…here’s how I do it.
Putting ink on the tip of a leaf then putting it on water causes the leaf to whizz around leaving a trail.
Have you noticed the shape of your urine stream when you pee? Here’s why it creates a chain. #funfacts

While these ‘magic mirrors’ look like mirrors…they actually project images. But how? #interestingfacts #SteveMould #chinesemirror
Remember the Rings Of Power opening sequence? It turns out I can recreate it using a vibrating square.

I think I’ve figured out why the smoke on incense burners falls instead of rises.
Can you bounce a bubble off a laser? I saw this video online and had to prove that it wasn’t fake. #sciencefacts
I have some new hypotheses about chain fountains, and I’m sure I can prove them right…
Did you know a cast saw can cut through a plaster cast but not your skin? The blade oscillates instead of spinning, moving your skin back and forth without harm. It scrapes away the rigid plaster bit by bit. How cool is that? (Don’t try this at home!) You can watch the full video on my YouTube channel.

If you boil alcohol in an electric kettle, will it ever turn itself off? Electric kettles turn off automatically when water reaches boiling point. But alcohol has a lower boiling point than water. So theoretically, you may think the mechanism that turns the kettle off automatically will never kick in because it’s based on temperature. Let’s look into this. I tried putting vodka in a kettle. Vodka is about 40% ethanol and 60% water. Water’s boiling point is 100 Degrees Celsius and Ethanol’s boiling point is 78 Degrees Celsius. The mixture has a boiling point at about 83 Degrees Celsius. When a mix of water and ethanol boils, the concentration of ethanol in the liquid goes down and is getting closer to pure water so the boiling point gets closer to 100c. The concentration then reaches a point that turns the kettle off. Now let’s try this with pure alcohol or more like 99% ethanol. The boiling point of ethanol is 78c, but the kettle still turns off. How does this happen? When You boil a liquid you can’t physically get it to reach a hotter temperature, the energy goes into turning that liquid to gas. The electric kettle detects the presence of boiling liquid not based on its temperature. The vapour produced by a boiling liquid creates pressure to force vapour through the tube to the bio metallic strip that turns the kettle off.
In my latest YouTube video, I talk about the fascinating mechanism that’s inside grasshopper legs: mechanical power amplification. It is found throughout nature and humans use it in tools and devices. Can you name some of them? This mechanism in a grasshopper’s leg allows it to jump high, overcoming limitations similar to those humans face. Humans use tools to overcome these limitations, such as making objects heavier or using devices like slingshots. Grasshoppers have their own version: a fancy exoskeleton that stores and releases energy quickly, enabling powerful jumps. Nature offers various mechanical power amplification mechanisms, like in the frog hopper or Trap jaw ant. Humans, too, use such mechanisms, seen in devices like compound bows. Despite these, exceptions exist, like clicking fingers or the slingshot spider using external tools for power.
Ever wondered how to make a black flame? In my most recent Youtube video, I’ll show you the cool science behind it—no tricks or colour inversion! Discover how sodium streetlights and a simple chemical reaction create this mesmerising effect. Plus, learn a weird trick that glassblowers use to make fire invisible. Watch the full explanation on my YouTube channel. #BlackFlame #ScienceExplained #SodiumStreetlight
In my latest YouTube video you can see my favourite physics puzzle project! The trick is getting three liquids that don’t mix and finding the right densities for the beads.
