Bubbles!

I did a quick test today to see how a bike pump would generate bubbles underwater and if the sounds would be any different from the compressed air cans. The stream of air is slower and lasts for a shorter time with a bike pump, but it is good for producing a controlled stream of larger bubbles. I will have a good listen to the material recorded and work out if it is worth doing a bigger session on this.
