Great - brings back childhood memories..!
After reading some reviews I was afraid this might not work, but it workds really well. My 5 year old loved it and it went up and down for about an hour. Make sure you only use baking powder NOT baking soda - totally different stuff. Baking powder makes bubbles with water but baking soda only makes bubbles with something acidic like vinegar. Also - make sure to fill up the powder compartment in the sub right to the top - pack it down hard if necessary and this will give it the weight it needs to sink. Make sure you give it a shake under the water to wet the baking powder and then be patient and it will work.

Not the best. Followed the instructions to the letter with my son and placed it into the bath tub. Worked now and again but not consistently. For the price though can't grumble and he's happy with it just as a boat.

Great - works well in warm water.
My little boy loves this, used multiple times in the bath and works well.Looking at reviews I wonder if the warmth helps the reaction.Would buy again

My grand child loved it
Excellent toy, worked perfectly in 30cm of water. My four year old grandson really enjoyed it. I can only think that the people who said it wouldn't work were not following the instructions.
