How about SF6? SF6 was used in some high end electrostatic speakers at one time. It would probably work in rather modest quantities compared to some of the other suggestions made. If you really want to go all out with noninnocuous gases, and if you are willing to run a bit warm, try UF6. That should work well!

Edmund is not far from me, so I go down to their store every now and again. Almost always they have lenses in their surplus area for REALLY cheap - like $2.00 a bag of 6 or ten or whatever. But, you can't be fussy if you're not there to pick them out. You might try calling the store - not the mail order number - and ask what they have in surplus. I have found the store personnel to be extremely friendly. They've got some of the BIG lenses from old projection TV's, but they are about $30. Great for projecting oscilloscope images. Another option is to get some magnifying glasses from one of your store's (if you are a museum) vendors. You can get good quality acrylic magnifying lenses for about 50 cents wholesale. Science and Nature has 3" diameter magnifying glasses for 0.85 wholesale and 1.75 diameter for about 50 cents each wholesale. These are fairly good quality for acrylics. Of course, you can't specify a focal length. For focusing laser diodes, I have used plastic lenses from those instant throw-away cameras. You can get them free from the local film developer. Again, the focal length is what it is, and the diameter is very small. For assortments, I would go to Edmunds surplus (call) and for lots of the same, I would get the magnifying glasses. Hope this helps.

It is a plastic thing with two large and two small lenses, a mirror, and a compass; a new improved version has even more stuff. Lots of museum stores have them. Depending on where you're located, you may be able to get lenses from projectors at a surplus store, or an otherwise broken projector at a thrift shop. Your school district audio-visual department may have a bone yard of projector and microscope parts. Page magnifiers are positive Fresnel lenses, a few $ each. Delta Education 800-442-5444 has some inexpensive lenses and often has discounts on packages of 10 or 30. Central Scientific 800-262-3626 has a good selection and better prices than Edmund. How about water (or other liquid) lenses? Clear plastic or glass containers with different curvatures can magnify but also project an image. See if a university chemistry department near you would donate some glassware; often they are scaling down their laboratory experiments and have surplus. An Exploratorium book Called Bending Light by Pat Murphy (1993) has ideas for ice lenses, jello lenses, and more. Can you use pinholes? good luck!

Here's one from my unused ideas collection. I kept coming up with additions to the basic idea over the years, and I fear it has become a bit large as an exhibit. ZERO GRAVITY One old method of creating lunar gravity is to lay yourself in a sling which hangs from a long cable. Lay horizontally in the sling and stand upon a nearby wall. If the wall is moved towards you until the force on your feet is 1/6 your earthbound weight, you've got lunar gravity. My idea is similar. Get rid of the cable and swing, instead lay on your back on a wheeled "garage creeper"; on some sort of low wooden plate having casters. If the floor is tilted, you will roll to the wall, and you can then stand upon the wall as if it were the floor, but with reduced "weight." Better: Place mirrors on the ceiling so you can see yourself standing in this enviroment, then add cues to the walls of the room to suggest that the wall you stand on *is* the floor, the wall above your head is the ceiling, etc. For example, put a rug on the floor-wall, put light fixtures on the ceiling wall, put sideways clocks, pictures, furniture, wall outlets, etc., on the other walls. The overall illusion is that you are standing on a floor, watching yourself in a wall-sized mirror, and a mysterious force is sticking you to the wall behind you. Jump into the air and you slide along the "wall", but with reduced (or possibly zero) weight. I've never tried setting this up, but I suspect the illusion would be pretty powerful & fun to experience. _____________________________________ <---- Mirrors || || || I || || / I======|| <-- Sideways furniture ||) I || || \ I======|| || I || || || || || || || ---------_________ ()HHHnnnl || <--- Person on back, on wheeled ---------_________|| "creeper" More! If this illusion-room had no tilt, it would simulate free fall. Various gentle tilts would simulate your weight on Moon, asteroids, etc. A room with a gentle concave floor and a huge central vertical cylinder would simulate the radial g-field of an asteroid (the cylinder being the surface of the asteroid, the tilted floor would slide you towards the central cylinder.) But how would anyone get off the cylinder? (Serious problem, equivalent to mankind getting off the earth.) Maybe climb up a ladder and exit through the perimeter, through the "sky?" Maybe build a semi-circular room rather than a complete circle, visitors exit by climbing into a "hole" in the "asteroid"? Of course decorate the floor and walls with star-filled space, the cylinder with rock texture.

Imagine an accurate full-scale space shuttle, but with visitors sliding around in free fall inside, pushing through hatches to play in the main bay, etc. The "garage creepers" would need very low-friction swivel casters, padding surrounding your head, articulated segments supporting your arms and legs, different sizes for different people or adjustable parts, etc. .....................uuuu / oo \ uuuu........,.............................

They do educational technology curriculum (as well as Dr. Katz on Comedy Central). Not that I would necessarily recommend it as is but, for the brainstorming value. I remember one of the three Minds on Science programs covering medical ethics - you are a scientist who has done a drug study with mice which shows improved memory. You might even be able to develop it into a treatment for Alzheimer's patients! The kids pick their priorities and rank them (this is for a classroom remember). You then get one of three choices and each one of these leads to one of two choices. At the end you find out how well you achieved your goals. The biggest problem I had with them is that a real person would get to do all the choices. The choices for this program were something like write a paper (with or without another really famous scientist), start your own company and try to develop the drug yourself (or continue working in a University) or tell the public in press conference or at a Scientific Conference (ie. to disclose your discovery or hang onto it for the patent). They will ship a teacher pack to ed. folks like us (it does use a laser disc BTW). The telephone # is (800) 342 - 0236 and they are based out of MA. This kind of approach obviously could work well in either as a computer or a maze exhibit or as a workshop. Another Minds on Science program lets you choose genetic research as a national priority and then you get to decide whether it is human or food genetics that should be emphasized. They have alot of fun with that one - the same 7-8 people protesting for both sides etc. Check it out!

Omsi has done this for their "Federation Science" exhibit - A Star Trek exhibit. No mirrors, just a carriage on rollers at a low angle. I thought it was sort of dull but probably helps to give one the idea of low gravity. Definitely a low cost way yet it is obvious that Omsi managed to spend a lot on it.

Otherwise there's just so much that flip-ups, feely-holes, models and multimedia screens can achieve on their own, without unaffordably high staffing levels. A particular challenge is to produce exhibits that offer as many degrees of freedom as those in physical science centres. There are many more interesting things to do with a ball hovering on an air-jet than with a pine-cone in a feely-hole, for example.

"How to have a Barbie Holiday" 1. Put up some mistletoe and kiss every plastic guy that stands under it. 2. Hug everyone without bending your arms. 3. On Christmas morning, drive your car through the living room. 4. Remember to turn your head 360 degrees at parties to make eye contact with everyone in the room. 5. Ask Santa for a whole new wardrobe. 6. Spend a romantic evening by the fireplace melting in your sweetheart's arms. 7. Accessorize, Accessorize, Accessorize. Oh and I saw a special on Barbie. There is a Barbie Liberation Force (the BLF). People go to stores buy Barbie, replace the voice box with GI Joe's and put it back on the shelf for some unsupecting parent to buy. Think about it Barbie says (in a dead voice) "Ready for Action!". While some GI Joe doll is saying "Let's go to the Mall". And let's not forget the Barbie that hated math. Cheers!
