I couldn't wait to try this. I told my husband that the smoke would go down instead of up and he looked at me like I'd grown a second head. He wasn't convinced but 10 minutes after it had been delivered we were sat watching. When the smoke started 'waterfalling' down we were like 2 kids on bonfire night marvelling at the sparks in the sky. I did a bit of happy clapping too close and stopped the smoke flowing downward but it soon righted itself. The Wild Jungle Waterfall is utterly brilliant and even after a few weeks I still marvel at the smoke flowing downwards. Fantastic!
