More from Experiment Tuesday

Robert Winston's Science Experiments is still our current go to book for our Tuesday Experiments.  Recent activities which I have managed to photograph (below) included Create a Cloud, Eggs-periencing Air Pressure, Split a Sunbeam and Launch a Bottle Rocket.  More that didn't get documented in photographs - Fizzy Fountain, Baking Soda Bag Bomb and Connection Currents.  So much fun!  

 

We've started a list of things we want to get a hold of in order to attempt some of the more 'advanced' experiments this book offers.  Some things look trickier than others to track down.  Please leave a comment if you have any useful tips for tracking these things down, ta!
