What you you think, a fire hose loaded with good german beer, that might liven up the party right?
I would keep the vinyl, or at least some of the more impt ones. You can give the lesser up to the flea mkt. Record them all so you can quit playing the good ones you keep.
I would create a make shift box to put the egg in the middle of with the straws reinforced with tape, string and the like. With that, I would suspend the egg in the middle of that with your rubber bands and string. The idea is to absorb the blow with the rubber bands and odviously you don't want the egg coming into contact with the ground. Wrap your paper around your box, have your packing peanuts placed on the bottom where the initial fall will be and so on, I'm sure you can make it from there. Good Luck!!
Home made discs are made of the same material is factory made. Polycarbonate. The big difference is that factory made is a stamped very thin layer of highly reflective aluminum. Home made is chemical based and burned by a high temp laser. The only problem I have found by the many many ones I've burned is that occasionally they get a fungus into the media (usually through the edge of the inner spindle hole) which will render them useless. But this is very rare. My recommendation would be to make two copies each. Use one as a working copy and one as a backup. If one fails, it's much easier to transfer data to date then LP to data since you have to record the LP to data in real time.
