I'm 44 yrs old and I got one of these for me years ago and I'm on my 3rd one at least. It's a huge hit at every single party with every age...EVERY AGE! Everyone loves it and the kids? you better have some time on your hands. The author gives a proven bubbbble recipe that works far better than any pre-made bubble solution you will find anywhere and there really are certain factors that make bubble making better. In the right conditions you can literally make bubbles the size of a car and much bigger with perfect conditions. It's all laid out in the book and well worth every single penny bt far! In lousy conditions, you'll make bigger bubbles than probably ever seen in your life. This is a perfect gift for anyone. I guarantee the rating on this won't go below a 5 and if it does, check the other ratings from the person who gives it less than a fiver. If this happens it will be from a bitter person with little joy inside so give that person some lovins'. Very few things in life are a lock for goodness and fun. The Bubble Thing is one of those. P.S. Do it in a manner that the soap that spills doesn't drop anyone and if done on concrete, asphalt, etc., hose down afterward. It's vvvvery slippery.
