Magnetic Coins: Singapore - Uruguay - Smallest Spins Piggy-Back - Robin Linhope Willson
The real Singapore 10 dollar coin ( dated 1983) and the real Uruguay 1 peso (dated 1989) are held in position vertically due to the presence of the ceramic block magnet sitting on a ruler above the coins. No glues have been used and there are no magnets between, or under, the coins. Similar ceramic block magnets are easily available throught the internet ( recently for as little as 42 US cents). In homes and schools they should be covered with non-magnetic material before use, or perhaps bought already covered in plastic or non-magnetic stainess steel (Magic Penny Magnet) This and related Singapore ten dollar coins are the largest magnetic coins of the over 600 magnetic coins from some 70 countries so far identified by Ciencias y Artes Patagonia (www.capat.org) based in Argentina. For a coin directory and further information, photos and videos, on this and related amazing, safe, cheap and accessible, schools science projects, for all ages and experience, see: http://www.MagneticCoins.info and Facebook: Magnetic Coins. By Robin Linhope Willson, formerly Professor of Biochemistry at Brunel University UK, the video is published by Ciencias y Artes Patagonia (www.capat.org) as part of the celebration of 20 years of Magic Penny Trust (www.magicpenny.org) educational projects.
