Marble race track - how to make

A fun way of making a marble track to keep your kids occupied  and enjoy

What you need:

A few toilet rolls
A basket
Some marbles

How to make:

Cut the toilet rolls into halves lengthwise and stick it on the wall in a pattern so that when you place the marble it slides around all the cut rolls and falls into a basket at the end. Your marble race track is ready.
You can also add some fancy stuff in between the tracks however you wish.
