Magic Matches!

Roll up! Roll up! Have any of you ever heard of jet powered matches? Well you have now!

YOU WILL NEED.

·        A container half filled of water. A washing up bowl is best.

·        Around six or seven matches.

·        Some dish washing liquid.

Instructions 

·        Put the matches in the container of water in a circle

·        Do not light the matches

·        Pour a little drop of dish washing liquid into the container in the centre of the matches.

·        Then boom! The matches fly off to the sides!

And now for the boring part:

The reason that the matches pull away is because the surface tension (top layer) of the water is tense and tight and when the detergent touches the top layer it breaks the surface tension and causes the matches to pull to the sides.
