The #solareclipse has come and gone! #HamOnt, donate your ISO safety solar eclipse glasses to us. HPL and @mcmasterphysics have teamed up with the Royal Astronomical Society of Canada - Hamilton Centre to collect, redistribute and keep out of landfills. hpl.ca/solar-eclipse
@HamiltonLibrary @mcmasterphysics I did not know about the 3minute limit on use of the eclipse glasses. There's one place in St. Catharines that is also asking for the eyewear for use in Latin America for the fall eclipse as residents might not be able to afford their purchase.
@HamiltonLibrary @mcmasterphysics This is dangerous @HamiltonLibrary - the McMaster solar glasses you distributed specifically state their lifespan is 3 minutes of continuous viewing. If there is a way to determine when that 3 minutes is up, maybe you could share that info for safety reasons.
