One of our favourite activities especially in the warmer weather are Bubbles!!
The BIGGER the better!!
I have a link to my bestest bubble solution here.
But we sometimes make the best bubbles using all sorts of different kit! Sticks and string for giant bubbles, bubble wands, bottle and tights. If you want a foam party well there is not much better than an old badminton racket!

What do you think makes the best bubbles??
