#1759: Meltingpoint

I hated using wax crayons at school. They almost never gave a good quality line when drawing and ‘colouring-in’ should be outlawed as a cruel and unusual punishment, in my book.

Today’s invention is a small improvement in the situation for schools that haven’t yet got to grips with felt-tip pens.

A small tube, wide enough to accommodate even those absurdly fat crayons, has a conical metal internal surface.

When the device has a crayon pressed into it, a small heater fires up as shown, melting the end of even horrid crayon stubs until a nice, sharp point is created (and without wasting all those sharpenings I used to hide in my desk).
