Jungle Juice

Ok, I made a post the other day about what I should make for a cheap jungle juice. It’s actually a 5 gallon not 8 idk why I thought 8. Now how can I mask the taste of the alcohol? I’m thinking about putting vodka, rum and everclear in it and I don’t want it to taste strong because I wanna it to sneak up on everyone lmao. Any tips? I’m also gonna put like 8 cans of Red Bull in there (two 4 packs).
