We used electrolysis (with sodium hydroxide NaOH solution as the basic medium) to produce oxyhydrogen and extinguished the candle by means of the reaction between hydrogen and oxygen. When electrolyzed, water decomposes … Continue reading A booming start of the year
Yesterday we attended one of the hundreds of Science Days venues open for free all over Belgium. Simon particularly enjoyed chemistry demos, even though he was disappointed that some companies … Continue reading Science Day in Belgium
Going for a walk quickly turns into yet another Physics experiment. “Here’s a challenge: what if you can force the ball down so much and induce so much horizontal motion … Continue reading Horizontal force
Simon really wanted to try building a capillary bowl – a version of a perpetual motion machine in which water circulates. Although aware of the fact that perpetual motion was … Continue reading Physics Experiments: Capillary Bowl
How does a periscope work? How does light travel through a periscope? How can you make a periscope yourself? Simon answers these questions in the video: Also tried to trace … Continue reading Physics Experiments: Simon builds a Periscope
Our new MEL Chemistry box arrived, containing tons of color fun! We have already tried two experiments. In the Color changing milk experiment, the soap touches the milk creating a very thin … Continue reading Chemistry Experiments: Colors (surface active agents and pH indicator)
Simon demonstrates chaotic systems using a bouncing ball that is being forced downward from some height.
Simon learned this trick from Physics Girl. Scientists actually perform similar experiments to mimic real hurricanes!
A really fun phenomenon that Simon learned from the Veritasium channel, based upon the Coanda effect. Simon later went on to repeat this experiment several times, even in the cold … Continue reading Physics Experiments: Hydrodynamic Levitation
Another take at our light trapping experiment, this time using a red laser pointer. We punched a hole in the plastic bottle and filled the bottle with water. As the … Continue reading Physics Experiments: Light and trapped inside the water stream
Caution: this is not a dessert, but ping-pong balls dumped in honey. Yes, we had to shop for a lot of honey yesterday to let Simon do the trick. It’s … Continue reading Physics Experiments: Viscous roll
Inspired by Physics Girl, here come a couple crafty color wheel experiments involving what Physics Girl calls “mind blending” (it may not be the real name) – mixing color wave … Continue reading Physics Experiments: The Color Wheel and Mind Blending
Geeks out of the box
