I am looking for someone to brush their teeth with me.
I found out that 9 out of 10 dentists say brushing alone won't reduce cavities.
Rotary dining table patentIn 1889, the idea of a "Rotary Dining Table" was issued a U.S. patent to a Black American inventor, Daniel Johnson of Kansas City, Kansas. His idea was to combine a "rotary table and adjustable chair adapted for saloons of sea-going vessels and of other descriptions, in which the occupants of the chairs may be served in rotation from one stationary base of supply without the danger and inconvenience incident to the person making the circuit of the table when the vessel is upon the seas, and also enabling the persons seated at the table to be served with dispatch." The entire table with its attached chairs was supported on one central rotating shaft - making the seated persons part of a human "Lazy Susan" type of turntable! (No. 396,089) |
