Antarctica - ice

I got this idea from itty bitty love, perfect timing! I asked Ebi-kun what it would be like to be a penguin jumping into the icy water, he said cold. So we set out a bowl of icy water and asked him to put his hand in it for as long as possible, he managed 4 seconds, this is most certainly a grin and bear it picture...

Then we got a plastic glove and covered it with lard, this time he kept his hand in for much longer, he described it as being a little bit cold but not too bad, I admit, I had to give it a go too - the second part, I don't need to know what icy water really feels like :o)

We then tried some other ice experiments. For this one float an ice cube in the water then try and pick it up with a piece of string - it won't work. Now lay the string on the ice cube and sprinkle on some salt, could to ten and try again - taaadaaaaa
In another bowl we set out 3 ice cubes, put salt on one, coloured water on the second and left the other one as it was then we watched to see which melted first. If we were doing this in the summer we would also do more ice cooking and ice treasure. Do you have any cool ice experiments/activities?
