I bought this Gazillion Bubbles Machine £15.99 for my godson on his fourth birthday. He had all his mates in a village hall for a do and this made them go crazy. Honestly, I had no idea. The only downside was a very slippery floor but the nippers were all having too much fun to notice. I can't recommend this toy enough for hours of fun and it can be wheeled out time and time again. Available from Toy's R Us and other large toy stores.
