    Introduction<\/h1>\n

    A flexible model to demonstrate the early development of the heart.<\/p>\n

    Model<\/h1>\n

    \"developing<\/a><\/p>\n

    Construction<\/h1>\n

    Made from several colours of knit fabric. The background grid in the pattern photo is 100mm x 100mm. Also prepare two long, oversized plastic bags. These should be able to be well sealed once filled. Double-bagging is a good idea.<\/p>\n

    The flexible filling is “Floam”. Floam is made from “Slime”, with added grated polystyrene. Slime recipes are readily available on the internet on kids make-it sites e.g. http:\/\/chemistry.about.com\/cs\/howtos\/ht\/slime.htm<\/a>. For this model we used the following recipe:<\/p>\n

      \n
    1. Make a 6 – 8% solution of Polyvinyl Alcohol (e.g. Sigma P8136, average molecular weight 30,000 to 70,000, H2O soluble) – tapwater fine, takes a while to dissolve (at least overnight) and can be sped up with a little heat<\/li>\n
    2. Make a similar volume of a 2 – 4% solution of Sodium tetraborate decahydrate – warm tapwater works well<\/li>\n
    3. Stir the PVA slowly into the borax – a clear gel (Slime) will polymerise<\/li>\n
    4. Pour off any excess water and knead the slime into a blob<\/li>\n
    5. Prepare a similar volume of small polystyrene balls (working inside a big plastic bag, grate a polystyrene container into small pieces) and knead into the slime – this is now Floam<\/li>\n<\/ol>\n

      Once the Floam is inside the sealed bag it will keep fairly well but may dry up over a few years and need to be replaced.<\/p>\n
