Help make a quacking noise in a wooden toy duck (mechanically, not electronically)

I'm in the process of recreating the LEGO wooden duck toy. I'm only working from a few images I've found online, however; I don't have an actual one to examine. On the originals, the axles operated a couple of mechanisms: the duck head pivots to open and close the beak, and there's a mechanism under the base (I'm assuming) that makes a quacking noise. I've got a pretty good idea how to create a simple cam for the head/beak movement, but I'm not sure how to generate a quacking noise mechanically. My online searches have proved fruitless. Does anyone happen to have one of these vintage LEGO ducks and is willing to snap and share some photos of the mechanisms? Or, does anyone have any good ideas how to make a quacking noise mechanically? My thoughts are a push/pull rod-type crank attached to an axle, but on the other end of the rod . . . not sure.

Home remedies, traditional remedies, quack medicine

I've been noticing a growing number of home and traditional remedies appearing. I don't doubt that some of them might have some slight benefit. But on the other hand, some are utterly worthless and a waste of time and money. I have a concern that less knowledgeable people may assume that because a remedy is listed here that it is, in fact, a reliable means of alleviating whatever ill they possess. I would like to see a flag/banner for all such instructables noting that the medical claims made in the instructable are entirely anecdotal and have mostly likely never been examined by any medical researchers. I'm not against the use of traditional remedies. I simply don't want someone to forego treatment by a physician on the basis of what they've just read here.

Violet Voltage?

Every so often, I see "violet ray" electrotherapy devices come up on ebay. They often sell for silly money, but occasionally one will sell for only a few pounds.Originally quack medical devices, they seem to operate in a similar manner to a plasma globe (gas discharges, high voltages). Does anybody know how they work? Is it worth getting hold of one to rip the innards out to get at the high-voltage supply?(Yes, I know they have "adult uses", but, really, it is the innards I'm talking about)

incomplete work

My science teacher was telling us one day about how he came to hate incomplete work. he had surgery on his appendix one day (for unknown reasons) and when he woke up his appendix was finished but the doctor didnt close him up. he called the doctor in but he said "oh i just forgot." he fired that quack and got a new doctor to close him up. tell me what you think of this story and also think of incomplete work...

Anyone have a review for a Sony "8GB USB Micro Vault CLICK Turbo" ( USM8GLX ) Flash drive? Answered

Yup, another find me question: one "8GB USB Micro Vault CLICK Turbo" review. I'm not necessarily asking you to write a review, but if you happen to this particular flash drive, it would be very welcome. Once again, i've looked around for quite awhile, can't really find a review anywhere. Is this because it's really old, really bad, or just uncommon? I'm thinking about buying one, any tips would be good. Also, any other Flash drive suggestions around AU$100 with 8GB, a decent read/write speed, and orange would be appreciated. ( i like orange. ) Thanks in advance. Quack.
