What can we say about these bubbles….they do what they say on the packet!! Blow your bubbles, wait for them to fall and then catch them in your hand! In our experience, we have found that these work best when you allow a couple of seconds for the bubble skin to ‘harden’ before catching them. They can leave a residue when they pop so please be aware on some childrens clothing. But to see a child catch a bubble and hold it is worth every second – believe me!
