If any type of animal swims in Straight or full concentrated "out of the bottle" blue pond dye they will be blue. Full strength blue pond colorant does stain skin. I know that from first hand use! The dilution of 1:1,000,000 does not stain swimmers. It has been tested by many pond owners.
If you wet your hands before pouring it into the pond it won't stay on your skin for long. I have a customer that said she can get blue on her just by walking past the bottle sitting on the shelf in her pole barn.
A friend wanted some to play with. O kay......... He used a needle and syringe to fill up ping pong balls so his grand kids could shoot them with a .22 LR and they'd explode. He did it at the private range that they belong to. A week later he got a phone call from the guy that was running cattle on it. He asked why the cattle all of a sudden had blue noses and blue tongues? Another time he did the same thing except the grass was a wee bit tall and wet at his farm where he used it. His daughter chewed him a new one. It seems the kids came home with blue shoes, socks and feet, plus the white goats weren't so white any more...... ROFL.
Another buddy wanted some to play a practical joke on a co-worker. I asked him what he was going to do. He said he was going to put some on his co-workers sweat band he put on his head/fore head. I told him that he could buy some from the store, but I wasn't going to get involved with that. After he found out how long it would last, he didn't do it.
