Holiday programme for Ascension Day and Whitsun: In search of the secret mineral code
Watch out sleuths! There are clues and tricky questions hidden throughout the exhibition. Use the mineral generator to see if you have found the right code. If it "spits out" a mineral, you can identify your treasure like a real mineralogist.
We also offer this programme on the long weekends at Whitsun and Ascension Day.
