So I've been putting the new high speed camera through its paces....
For a long time I've enjoyed tormenting students with water in a vacuum tube. It makes a chinking sound... but why?
Now for me.... you gotta bear in mind Ive been working with vacuums for over 20 years..... to me this is like watching the sun rise and seeing the earth spinning. But its always fascinating to see people reaction to this. Maybe I should do a react video on it! :-)
Many thanks to all those who support this
