These are a must have if your kids enjoy bubbles. The Gymboree Bubble Ooodles set is terrific! The bubbles are little, there's loads and they linger longer! What's not to like about that?! You can purchase them at any Gymboree store or on their website. The solution is better than normal bubbles and I'm assuming it's because of the glycerin content. They will leave behind a (cleanable) trail, even on the tops of your kids heads! Here's a good review I found that tells you everything about them. Have fun blowing bubbles this Spring!
