More ideas to come. * ===== Projects I am interested in ===== * [[project:kilt:start|Kilt workshop]] – I shall learn sewing. * [[project:presentationcenter:start|Presentation center]] * [[project:biolab:start|Biolab]] – I might learn something about those green or moving things. ===== Other stuff I sometimes do ===== * Trying demo experiments I know from the internet. * Juggling (not related to Brmlab). ===== Demos ===== These are small (well known) experiments often done in school that I either tried or want to try. ==== Tried ==== * Sugar in sulphuric acid – sugar loses water, turns black (to carbon). * Potassium permanganate and glycerol – self ignites, starts burning. * Cotton wool and superglue – this is supposed to start burning.
