The Last Rainbow Bubble

Its the last I promise, well for now anyway.

I thought the first bubble image wasnt colourful enough

I thought the second bubble image had the colour but the bubble wasn't the right shape, looked a bit deformed.

So tonight, instead of water I used glycerin. it held shape lovely and I liked the colour. So I think for now this is the best I can do.

I thank every one for their opinion so far and would like it again on this one.
