Looking for instructions on how to make a "body bag" to simulate g forces.  Have done this activity at a couple of different science centers, but have lost my schematics on how to make the bag.  Hoping someone out there has done this.  Basically it's a large body bag made out of usually 6 ml visqueen.  People get into the bag, sit on a chair and holding bag tightly closed around their neck get ready to experience "G" forces.  The bag has had an area prepared to hold a shop vac tube...the shop vac is turned on to suck air out of the bag which collapses tightly around the body.  Force is felt, giggles insue, cheap, easy....and it seems we did this all with duct tape, visqueen, a little bit of cardboard and PVC to construct the area where the vac nozzle is inserted.  Thanks in advance to anyone who can help me out with the details so I can get this made.
