I think the ravers generali just lick the walls of the mini biodome. I see a couple of them get out and look really scared and confused but if you direct them back into the little dome tent they seem to be fine.
I am a 37 year old raver who still loves the light toys. There should be no problem bringing in glowsticks. Last year when security was checking my backpack, he took a look at my Strobe FX lights (LED type lights on a wand) and he said "what's this, e-tard shit?" so I laughed "yep, E-tard shit".
He laughed, let me through and said "Have a good time man!"
