Air Bomb??

...if you are not quite sure this is a ballon being popped under water!

My daughter and I had great fun popping about 30 balloons. The water sloshed everywhere, thankfully I'd put my flash gun in a clear plastic bag and my camera was far enough away. Popping them was harder than expected and getting the timing right was difficult.

However with this beaut' we got it just right. The tubular type yellow balloon popped and you we snapped it just as the rubber broke. You can see the thousands of bubbles still in the shape of balloon.

We got two others like this out of about 30-40 balloons. Now to go back and mop up the spillage :-)
