How do orange-peel-powered boats work?
« on: 23/03/2009 21:38:06 »
Hi) When I was a child we often placed a small parts of orange peel into a pools that left after the rain on a ground. These peels then starts floating in one direction like a small motorized boat and it was a rainbow trail left behind peel, just like film that left from gasoline/petrol on a water surface. Can you explain this somehow, please?)) Well, not about film itself, but about movement))) What is it and how does it work?))

This example uses soap rather than oil (of orange) to alter surface tension ...

I remember, as a child, seeing the same effect where a little bit of tree-sap of the right type and consistency would produce the same effect.  We'd put a little sap on the end of a small straight twig to make 'speedboats' and if we were lucky, they'd go in a straight line instead of around and around in circles.  They left the same sort of trail behind them.
