For a truly healthy diet for your kids try going “screen free” for a couple of hours every weekend.

Have you heard of a marble run, a ball run or even a cresta run?  This is the same but a much muddier water version!  First locate a large puddle (should be easy). Take some old plastic bottles and containers out of the recycling bin and cut them up to make channels and funnels.  Use some forked sticks or other containers to support your “run” and see how far you can make the water travel?

Try making a little boat out of a leaf or a few sticks tied together and have races with your friends.

Or how about a water run team competition kids v adults!  Each team designs a run and  the winner is the one which collects the most water in a container at the end in the shortest time?

Be careful not to get too cold and wet, have some dry gloves handy and make sure you wear some waterpoofs as it’s pretty freezing out there.

Have fun designing and don’t forget to tweet photos of your ingenious runs with the #screenfree and #outdoors for the chance to win a signed copy of one of our books.
