Chouette gadget inventé par Paul Matisse dans les années 1970.
J'en ai trouvé sur le Net à plus de 400$ !!!

Kalliroscope: rheoscopic fluid reveals the convection currents generated by the heat emanating from fingertips. Invented and produced by Paul Matisse in the 1970s, suspended microscopic flat crystals of guanine reflect light and allow visualization of the fluid's motion. This rheoscopic fluid is special in that the guanine crystals are the same density as the tetrachloroethylene liquid so the crystals never settle to the bottom making the fluid reactive to showing the slightest movement. ➡️ Follow the link in my profile for more info on where to get many of the amazing objects featured here on @physicsfun #kalliroscope #matisse #kineticart #rheoscopicfluid #rheoscopic #Matisse #convection #kineticart #fluiddynamics #1970 #1970s #Calder #kineticsclupture #kalliroscope #physics #physicstoy #art #psychedelic #lavalamp #science #scienceisawesome #fluiddynamics #rheoscopic #physics #physicstoy #convection #convectioncurrent #science #perchloroethylene #tetrachloroethylene #1970
