I bought these for gifts after finding the older version at a garage sale. The bubble wands work great and seems to attract everybody. My friends laughed at me when I pulled my bucket of bubble solution and bubble wand out of the car, but as soon as they seen the size of these bubbles and the way they bend, stretch, deform and float around, they couldn't get enough. You can make gigantic bubbles with the wand, but you have to practice the release of the bubble. When you figure out the tricks(there are a couple)no one will be able to resist gawking for hours. Adults laugh at first, then remember how much they still love BUBBLES. If you use this at a park, you will have countless fans. The one thing that's a bit of a problem is the recipe for the bubble solution. I find that a 1 to 10 mixture is better than the recommended 1 to 12. Also, the bigger the bubble the harder it has keeping it's shape, but that can make for some great fun and wacky bubbles. No more than a light breeze will be needed to make most of the bubbles but especially the large ones. Any moderate gusts and they pop. The book has good background information but the recipe will need to be adjusted per your own experimentation. Have fun, I know I am.
