Unbelievable!!!6 years old girl and 9 years old boy First time diving without HOW TO KNOW SWIM!!!!

My kids are never ever known How to SWIM, never take a swimming class. But I just put them in swimming pool with 3ft. And spending time with them in the pool and try to help them practice swim. And today it's the first time for them to dive and pick the coins up after I dropped the coins down....UNBELIEVABLE THEY CAN DO IT....BUT DO NOT LEAVE THEM STAY BY THEM SELF because it's not save and dangerous for kids do not know how to swim!!!!!
