I've been wondering this for a while now... My best idea would be to throw it inside some speakers. I got an amplifier, works good.
Get a road case for it amd hide it under your house(if its on beams) other than that i wouldnt waist money on something that you rents can find and destroy.
I was going to suggest this too! I have an old backpack that I don't use anymore, it just sits in the corner of my closet. Nobody suspects a thing
Yup, best idea yet. Go to the pawn shop and get the biggest/cheapest POS home stereo speaker and hollow that bitch out. Make it an awesome sliding door on the back that allows for quick access. Don't forget to actually run wires to it from your computer/stereo to complete the best in-plain-sight marijuana paraphernalia hiding spot ever.
-Take your pillow out of your pillow case -Put your Bong in pillow case -Fill up with packing popcorn -Zip up pillow case Thats what I do for my 20inch weedstar bong
Empty computer case. Take the side off and take enough pieces out to fit the piece and any other miscellaneous stuff.
^Another person who doesn't realize how big a 20" tube is... or has a monster computer tower from the 90's
If you have a lot of shoe boxes cut out the side of two of them and put them together, or put them in a big box in your closet if you have any...
