Home made swimming pool diving toys

Just a fun and helpful idea to share:
My son loves to dive in the pool looking for dive toys that we have purchased in the past. I'm forever buying new ones as the old either get lost or broken.  So i came up with this idea the other day and it went over big with my son and his friends.

I bought mini bottles of water and added food coloring and to make them heavy i added decorative glass stones.

I'll also did it with out food coloring and used larger bottles

 Both worked GREAT....
