Last Friday I got two postcards: one from Japan and one from Slovenia.
The card from Japan shows an exhibit at the Osaka Science Museum. The Osaka Science Museum was opened in 1989 to mark the 100th anniversary of Osaka City. It shows many interactive science exhibits and daily live science shows.

Thank You very much Keiko!
