At the dentist

Today we were with the kids in the museum at the "Time Street", where we met many interesting items, artifacts etc. some of them as old as St. Petersburg. After the 18th and 19th century we entered the 20th... this is how it looked like at the dentist 50 or more years ago.....
My kids never have been to the dentist yet, so probably it was not that exiting or even horrifying for them than to kids how already met their dentist.... ;)) For some more impressions.... http://www.youtube.com/watch?v=ZSJSzLWsUTc
