english: So we take that periosteum layer and we developed a way to inject underneath it a liquid that then, within 30 seconds, would turn into quite a rigid gel and can actually lift the periosteum away from the bone.
non_english: Tako da uzimamo taj sloj pokosnice, i razvili smo način da ispod njega ubrizgamo tečnost koja se onda, za 30 sekundi, pretvara u prilično čvrst gel i tako može da odvoji pokosnicu od kosti.
