P4-7 Science and Engineering Club

Thanks to everyone who attended Science Club on Thursday. It was really exciting to see what happened to the colours in the different kinds of milk when we added a drop of washing up liquid. Amazing!!

Well done for working really well together and special thanks to Jessica for helping wash up. I have added a brief reminder of the process below.
Milk Colour Explosion
Milk is mostly water but it also contains tiny droplets of fat suspended in solution (the milk). The secret of the bursting colours is the chemistry of the drop of washing up liquid, which weakens the chemical bonds that are holding the fats in the milk. Part of the soap attaches itself to a fat globule in the milk and the fun begins.The molecules of fat bend, roll, twist, and contort in all directions as the soap molecules race around to join up with the fat molecules. As the soap becomes evenly mixed with the milk, the action slows down and eventually stops.

  1. Science club sounds like great fun!
    We enjoyed hearing about how you made the big blob of blue gloop a few weeks ago – it was very strange to touch.
