Hot Ice (Sodium Acetate) Experiment Success
Sodium Acetate: a chemical compound made by combining acetic acid and sodium bicarbonate, or simply just plain old vinegar and baking soda. It is used as a flavouring ingredient in snack foods and in hand warmers. Chemical formula: CH3COONa.
This is our second attempt at experimenting with sodium acetate (also known as “hot ice”). The aim was to create a tower using a solution of sodium acetate and water. It was a success!

Home Made Speaker Experiment
Here is an easy way to demonstrate how sound is reproduced electronically.
This is how this simple speaker works:
(Note that on most speakers the magnet is stationary and the coil is attached to a moving cone.)

How an elevator affects magnetometer trace
I made this video to show how an elevator affects the magnetometer trace. This is something, for those using a magnetometer to detect earthquake precurors, to be aware of. Notice the characteristic of the trace. Not to be mistaken as an earthquake precursor.
(Editor’s note: Simon is using the magnetometer described in this post. He lives on the 7th floor and sees very little traffic noise on his daily recordings, but at certain times of day he had been plagued by some very regular signals, always about the same size. In this video he shows how he finally tracked down where they’re coming from.)

This is a video of a first attempt at experimenting with sodium acetate. Experiment performed in Taipei, Taiwan.
It was a fun experiment to do. The result wasn’t exactly what we were going for. Better luck next time.
