Book Suggestion: The Alchemy of Air
lowell Thomson | Fri, 01/05/2018 - 03:08
One of my goals for 2017 was to read more chemistry non-fiction. I accomplished that with three and a half books read. That doesn't seem like much, but given how busy I've been lately it was quite an accomplishment! I offer a brief review of my most recent book here, "The Alchemy of Air" by Thomas Hager.
Scrub Daddy Science
Tom Kuntzleman | Wed, 01/03/2018 - 18:20
The science behind the incredibly popular Scrub Daddy sponge is investigated. Part of the appeal of the Scrub Daddy sponge is that it changes from soft to hard depending upon temperature. This allows a single sponge to be transformed into a hard scrubber or soft sponge, depending upon the temperature of water into which it is placed.
