There’s nothing better than cooling off in an outdoors pool on a hot summer day. Well, one resourceful dad managed to turn a fun day out into a learning experience for his kids. It may sound strange at first, but dad used the family’s swimming pool to conduct an awesome science experiment trying to replicate a phenomenon called “constructive wave interference”. This is something you need to see to believe, so take a look and don’t forget to share. With summer closing in, we all could use some fresh ideas to entertain our friends and family, don’t you think?
