The sweetest, saltiest love song about how sodium and chlorine fell in love…
A cute tune by the McGarrigle Sisters, telling the heartwarming story of salt – sodium and chlorine – falling in love.
Perfect for high school and university chemistry lectures, complete with valences, electron shells and ionic bonding of NaCl.
Y’all have a great christmas and a very merry perihelion!
The Rubens Tube is a really complicated demo that seems simple. Once you start thinking about it you realise that sound antinodes are points of oscillating pressure, so the flames shouldn’t be stable peaks – they should be going up and down at the frequency of the wave!
And if you change the gas pressure a lot the nodes and antinodes reverse position! Wish I’d thought these points through before Derek asked me to film this!
