Helen and Charlie were in for an unnerving underwater adventure -
The girls were to dive under the water and find the 12 stars which were hidden in five domes set on the dining table, ‘fire place’ and a crockery cabinet.
All the stars in the domes had to be collected only using their teeth and mouths, but they could use their hands when collecting the stars from the fireplace.
Once they put their heads in the first dome they could not come out of the water, if they did their part of the trial was over!
