Sign of the Cross Scuba

Whenever my friend Kenny and his Dad go scuba diving, they dive down to the bottom of the ocean and kneel on the sand. They both perform the sign of the cross, where they take their right hand and touch their forehead, move their hand down to their sternum, and then cross to their heart and the opposite side of their heart. After they perform the sign of the cross, they look up to the sun. They perform this ritual every time they go diving together in order to keep them safe while they are under water.
