So, technically it is not an art project but it is a fun science experiment… how does an egg look like without the shell? The raw egg I mean… like a gooey bouncy… try it for yourself. You need couple of raw eggs (they can break easily once you start exploring them, so making more is a good idea). You put them in a jar with a lid and pour vinegar over them. The just let them stand 2-3 days… drain the vinegar, Raise them with cold water and let the exploration begin.
