Any one who can tell me what this item from the powerhouse collection is will be in the running to win a book prize. A second book for the first person to explain the physics phenomena it is used to show.

check the comments for clues – final answer tomorrow.
Something happened so we couldn’t do this weekly. But here is another microscope image. If you are the first non-Powerhouse staff member to identify the object in the image you will receive a family pass to the museum.

This is a new page for the blog. Each week we will put up a mystery micrograph image. The first 5 people to work out what the object is will receive a free pass to the museum.
1. You need to be as detailed as possible in your description of the object.
2. Judges decisions are final.
3. Prizes awarded to the 5 comments with the most correct detail.
4. Where more than 5 comments are submitted with equal detail the first five posted will receive the prizes.
5. Only one correct entry per email address will receive a prize.
6. Prizes consist of a single adult pass to the Powerhouse Museum, Sydney.
If you come back later in the week there will be clues to help if it hasn’t been worked out.
Leave your description as a comment on this post and we will choose the winners according to the time the comments were left.
So here is the image for the week from Monday September 25

As a number of people stated this was indeed an image of the Australian $20 polymer note. This is on the side with Mary Reibey – and is an image of a property she owned. The reserve bank has details of the Mary Reibey story. The Australian polymer notes have a number of security features to thwart counterfeiting – two can be seen in this image
Slightly raised printing that can be felt with the fingers is used for the portraits and other major design elements.
Intricate multi-coloured fine-line patterns and images appear on each side.
The Polymer note technology is now used by countries all over the world to protect currency.
Finally congratulations to Harry who correctly identified the image – luckily the only person to do so – he gets a family pass to the new Great Wall of China exhibition at the Powerhouse. Next time Harry to be elligible you will need to post your answer to the blog as a comment.
