My fantastic MIL has just given us one for our dd that she has had for ages, but I want more!
It is like a fan - each section has lots of holes in it. You close it up and put it into the bottle, then when you take it out you open the 'fan' and wave it about - you get absolutely masses of bubbles.
My sister is getting married in the summer and they're not allowed confetti, so she's asked me to get bubbles for the guests instead. These would be fantastic, if only I could find them. My MIL got our in her local Tesco, but it was ages ago and they don't have them any more. If you've seen them anywhere please please let me know.
Thank you all!
