I watched a programme about how monkeys are so alike to humans, not just because primates are the closest to humans in evolutionary terms but because of the way they act, they do typically human things like jumping into water pools from great heights just for the adrenalin rush!
To fix this: Use a small spray bottle, baby shampoo, and water. Fill the spray bottle 3/4 of the way full with shampoo, and then add water. Shake. Spray on fronts and insides of goggles, and rub. This recipe is from my coach and it works AMAZINGLY!!!!
