Magic Bubble Show

As part of science week our class went to see an amazing bubble show yesterday in the Teachers' Centre. We walked there and back so we got plenty of exercise and we had yet another opportunity to use our safety rules for crossing the road. We got a chance to look at giant bubbles and we observed that all the colours of the rainbow (red,orange,yellow,green,blue,indigo and violet) are visible at first in the bubble. When all the colours disappear the bubble is about to burst. We had great fun predicting when the bubble was going to burst. Interestingly the bubble always formed the shape of a sphere. The man used different shaped hoops and they were different sizes also. If the hoop was very big then the bubble was very big also. We also saw a bubble filled with smoke, a bubble within another bubble and several bubbles joined together to make a caterpillar. To make the bubble mixture you will need a fairly large container filled with water. Add 1% glycerine and 4% washing up liquid. Mums and Dads will need to give a hand making the mixture!
