Yep. Lots of guys doing this exact thing. Even plain ole 100 proof will hold quite a bit.
In Texas I can buy Everclear in like fucking grocery stores and shit, theres drive throughs and shit too. Its perfect for our purposes, just plain, pure, nothing in it but alcohol.
Use the highest proof you can get with the least other shit added into it, flavoring and sugar and such.
Measure with a syringe. Dilute in syringe with water so you dont gag, squirt and swallow.
