Explorering boundries by priecing barriers. '2.6g 329m/s' the name of this project, the performance standard for bulletproof vests. 2.6g 329m/s are the maximum weight and velocity of a .22 calibre Long Rifle bullet from which a Type 1 bulletproof vest should protect you. Spidersilk thread is relatively much stronger than steel and can even be made by a living being. Woven it would be capable to resist the impact of a bullet, much like a bee on the spider’s web. If human skin would be able to produce this thread, would we be protected from bullets? Together with the Forensic Genomics Consortium Netherlands I take the acid test: by implanting transgenic spider silk in the human skin and letting a bullet do its work. By implementing this bulletproof matrix of spider silk produced by transgenic goats in human skin I want to explore the social, political, ethical and cultural issues surrounding safety in a world with access to new biotechnologies.
