Antibubbles
Simon having fun making antibubbles – bubbles that have water inside them instead of air. Learned this from a Physics Girl video and this online instruction: https://www.antibubble.org/page2.html

Object inside rolling cylinder
Simon took a cylinder and put a chalk inside. When the cylinder rolls, what will the chalk do? Will it move and how will it move? And more importantly, why? … Continue reading Object inside rolling cylinder
How much iron is there in your favorite cereal?
If you put a cereal flake in a bowl of water you can steer it with a strong magnet. The magnets above aren’t strong enough, but the really powerful ones … Continue reading How much iron is there in your favorite cereal?
Experimenting with electromagnetism
Here Simon tried to induce a magnetic field by allowing electric current to go through a conductor that is normally not magnetic (copper wire). The green stick is a magnet … Continue reading Experimenting with electromagnetism
Some basic molecules
Above: “Mom, look, this is what we breathe in and this is what we breathe out!” Looking for a better organic chemistry set now, with plenty of carbon and hydrogen … Continue reading Some basic molecules
The Best Shape for Train Wheels
Simon explains why train wheels are actually shaped like truncated cones. Inspired by a Numberphile video about stable rollers. The wooden slopes for the experiment Simon designed himself and his … Continue reading The Best Shape for Train Wheels
The Universe is made of ones and zeros?
While riding in the car: “If the Universe is not random, it’s made of zeros and ones! I worked it out because quantum mechanics describes elementary particles as probabilities. So … Continue reading The Universe is made of ones and zeros?
On the train
Simon waiting patiently as our train was halted for over an hour due to the extreme heat: “If you pick four atoms from the Universe at random, then I would … Continue reading On the train
Slowing down the time
The first thing Simon said this morning was: “Mom, do you know that if you keep moving, you get one quadrillionth of a second per second younger than if you … Continue reading Slowing down the time
The three stated of matter (plasma not included)
Inspired by a Numberphile video with Tadashi Tokieda.
Convex vs. Concave Mirror
Simon learned this from Tadashi Tokieda in a Numberphile video called “Reflected Cats” and recreated the experiment.
Is the Universe random?
Simon, looking at the dust particles in the sun: “Is brownian motion random? If we look small enough, we might see something deterministic… but it might also be stochastic. What you’re … Continue reading Is the Universe random?
