Bett 2022

 Visited the Bett show today. Largely disappointed. only about 1/4 of the exhibitors. Normally I come back with want this or that - not this time. Not that surprising due to circumstances.

Umbrella Drop

 Doing the umbrella drop experiment. Two identical umbella's, fall at the same time, but if one is opened ...

Bernoulli's Principle

 Bernoulli's Principle Faster air = lower pressure. Looking at everything from fun items to planes flying and wind and air pressure. #iteachphysics

Spectrometer with Fibre optic scope

 One of the problems of the students using a spectroscope to observed the emission lines is that they usually can't see them, but using the @pasco spectrometer I can put the image on the board and we can calculate the limes easily

A Far Infrared Picture

 My Phone with a FLIR attachment allows me to take and show heat pictures to the students, showing the shadow of a hand print on a table of how much heat the white board gives out.

Faradays ice Pail

 More fun with the Van De Graaff Generator this time with Faradays ice Pail #iteachphysics

Black Light

 

Using a UV light to show up the invisible parts of bank notes enthused the students some claiming they hadn't seen a £50 note before and seeing that it was genuine. I was glad all the notes we looked at were genuine.
