Willow brought along the most wonderful experiment we all took part in.
First she put her finger into iced water and we timed how long she could keep her finger in the water before having to take it out.
Next she put her hand into a plastic bag filled with fat, simulating the layer of fat around Polar Bears and then re timed how long she could keep her finger in the ice water.
Willow's hypothesises was that the fat would surround her finger and keep it warm so she would be able to keep her finger in a lot longer the second time.
Both Willow's second time and Bradley's second time were effected by play and home time... but you can see that the results pictured below supported Willow's hypothesis.
Many people thought they would be able to hold their hand in the cold water for 20 years... they just wanted to do it longer than the last person.
We also noticed that if the fat formed a full layer around your finger it worked better than if there were gaps in it.
Thanks to Willow, Hayley and Charli for an excellent first experiment!
Willow we had a great couple of photos of you doing this on your iPad - if you could send them to Mrs Maw I'll add them up here too.
