Eddie, a Science Museum Explainer, on demonstrating science in six seconds.
Are you following the Science Museum Learning team on Twitter? We share lots of interesting facts, ideas and suggestions for teachers (and for anyone else interested in learning about science as well).
We post Vine videos highlighting some of the best experiments and exhibits that we have at the Science Museum. I make these short six second videos, and I thought I’d take this opportunity to share my favourite videos with you.
Alka seltzer rocket
The alka seltzer rocket is part of our Materials demo. The film canister is fired into the air when gas produced by the alka seltzer tablet expands inside. This was quite a tough Vine to film as the launch is a little unpredictable!
Cornflour on speaker
This experiment is part of our Sound demo, although it’s actually an experiment that demonstrates a material phenomenon. This substance is cornflour mixed with water, which is a non-newtonian fluid. When sound travels through the mix, it gives it energy to lock together in a solid shape.
The Newton’s Wheel is part of out Light Demo, and is one of our most popular Vines to date. This very simple experiment shows how white light is made up of all of the different colours of the rainbow blended together. When the wheel spins around, our eyes can’t differentiate all the different colours, and it appears as white.
You can find the jumping ring in Launchpad, in the Magnetism section. The metal ring is launched into the air by a powerful electromagnet at the base of the pole. This experiment needed the help of Explainer Ben to press the button for me, so we could get the jump in shot!
This smashing experiment is part of our Supercool schools event, which is all about heat and its effect on different materials. We use plenty of liquid nitrogen in this show to demonstrate some of these temperature changes, such as letting our friend here, Plasticine Peter, “cool off”. This is my favourite vine that we’ve ever produced.
CO2 in Bubble Mix
When you put solid carbon dioxide into water, it begins to sublime. This means it goes straight from a solid into a gas, without going through a liquid phase. When we sublime it in bubble mix, it makes some incredible CO2 filled bubbles, which in our tube, makes a Bubble Volcano! It also created a bit of a mess on the floor!
We’ve done almost eighty Vines now on the channel, and there’s more on the way, so make sure to stay tuned to @SM_Learn for all the best experiments that the Science Museum has to offer, in six seconds or less.
