when was the first potter's wheel invented
Potter's wheel The earliest forms of the potter's wheel (called tourneys or slow wheels) were probably developed as an extension to this procedure. Tournettes, in use around 4500Â BC in the Near East, were turned slowly by hand or by foot while coiling a pot. Only a small range of vessels were fashioned on the tournette, suggesting that it was used by a limited number of potters.[1] The introduction of the slow wheel increased the efficiency of hand-powered pottery production.
Fidget spinner As of 2017, the patent status of the various fidget spinners on the market was unclear.[8]
