So I'm a first time poster. It's been a few years since I rolled, but the wife and I and are planning a trip soon to roll.
I've been searching the net for some useful information and came across this site. Very cool and informative.
This thread has some great ideas and I thought I'd repay the thread with some old tricks of my own.
1. Someone has already mentioned "firewors" glasses, or "rainbow" glasses, but they are cheap and flimsy. What you really want is called a "Spectrix Laser Visor" this is the shiz for light shows. Just google it, and you'll find several sites to purchase them.
2. Hear Something That Makes No Sound: while standing, have someone with a metal slinky put the last ring about half way back in your mouth and bite down slightly on it. Look down and close your eyes. Have the person very gently tap the slinky at intervals, and you CAN'T hear the sound but you can mentally feel or hear the sound of the slinky. It sounds like a light-sabre in an echo tunnel all over in your head and body!
3. Face/Body Melt: 2/3 People
Take a sponge (we actually used a toy ball made for water) and absorb as much water as possible. Have the persone receiving the melt take of his or her shirt (leave the bra on ladies) and lay back on a couch or something where there head can hang off the edge.
*OK If you have a portable fan (the kind you would have for a really hot day) it makes this experience even better. *
Once the person is comfy start out with a head massage. Then once he/she's into it take the sponge and slowly squeeze the water out over the persons head, and face then work your way down to the top of the chest. (If you have a fan blow it on the person as you squeeze the water out. So awesome.)
4. Playing on a trampoline is amazing.
5. Laying in the grass or leaves with your shirt off.
6. Winter specific- Sleighriding.
7. Snowangels
8. Eating Snow
9. Beer Pong with with water instead of booze in a fun way to keep hydrated.
I hope I didn't repeat much here, and you guys enjoy these things as much as we did back in the day.
