Water is given all around the sand box and those bottles get thrown away like candy. Going to the gym to work out is a good hobby. There are a lot of suplements that the military installations sell or you can get them online and putting them in water is the easiest choice but those little bottle mouth holes are a big pain in the a.. to get those supplements inside them. Getting a funnel there is another big issue but we came up with this idea.
This is an improvised funnel that we used in Iraq and even back home is easier for me to use because it goes screwed on almost any water bottle. Any question please feel free to ask. Thank you.
