A swim through a Finnish pond
The areas that were covered with thick ice sheets in the ice ages
that ended some 12,000 years ago are covered with lakes and ponds of
many sizes, many of which are a beautiful blue or green colour, though
in the case of spotted lake (see http://bit.ly/29kJQzp) something more surreal can result. Loz.

Mimosa pudica (from Latin: pudica ”shy, bashful or shrinking”; also called sensitive plant and the touch-me-not), is a creeping annual or perennial herb often grown for its curiosity value: the compound leaves fold inward and droop when touched or shaken, re-opening minutes later. The species is native to South America and Central America, but is now a pantropical weed.
