From left to right, you can see MRSA, influenza, chicken pox, e. coli, and HIV.
Go ahead and take a lick! They're perfectly safe. Artist Wei Li made these popsicles just look like deadly pathogens. They're part of a project that he calls Dangerous Popsicles. Li explains that he wants to create a confusing sensory experience:
Before tasting with your tongue, you first taste with your eyes and mind. The popsicles are nothing but water and sugar, but ideas of deadly viruses and the spikiness of cacti are enough to stimulate your senses, even before your first taste.
He used a 3D printer to build models, which he then used to create popsicle molds.
In addition to the microorganisms, Li also created several cacti. They might not kill you, but you should check for spines before eating.
