Dental floss and beer bottle fishing reel part 2

Me and my son went back down to the drain in the woods to show a better video of the dental floss and beer bottle fishing reel.

 

That is murky water. Are these you inventions or do you read about them and try them out?

 

I read about them when I was a boy scout and have been making them ever since the water is dark because of the tanic acid from the trees it make it easy for gators to hide and ambush prey
