Special offer: Solar System scale model

English and American Solar System scale models now very cheap!

In 2003 we prublished three Solar System scale models (scale 1:100 billion) consisting of 16 cards, full of information AND the distances to the Sun and the sizes to scale.
The Dutch scale model was very succesful and was recently brought out in a new design and set up (a basic set and a supplemental set, see the Dutch page for pictures).
The English scale models (English with metric information, and US with miles, inches etc.) were never a success, like the English BIY Star Wheel and Sundial, because we don't have partners for these products in other countries.
However, they are still very usefull to teach young and old about the distances within and the emptiness of the Solar System - and beyond! Granted, Pluto is no longer called a planet but a dwerf planet, and many other ice dwarfs were discovered after the publication of the products. Therefore there are new cards available for many ice dwarfs that were discovered after 2003, a few of them are now also dwarf planets. These extra cards can be dowloaded for free here.
