You could even make it jerk around when someone went near the tube... I don't exactly know how this would be possible, but I'm just throwing out ideas here, haha. Imagine your new GF going up to the tube... JUMPS RIGHT AT HER.. AHH..
One question... what would be the best facehugger to buy? There are a few on ebay, one good one is the "CretureFX" one. Can anyone attest as to the quality of it, and how good it would look in a tube? Also, how does the finish on the facehugger not come off in the liquid? Is it some special liquid, or a special finish on the model itself?
