Go to home dePOT.

Get a piece of PVC that is big enoug to slide your bong in.

Also get 2 endcaps that fit the pipe.

Cut it to the right length.

Now you not only have a safe hiding spot... seriously pvc pipes in the basement are like towels in the bathroom! They are SUPPOSED to be there so no one notices them... you ALSO have a safe way to carry it around with you when you move off to college or whatever.
