Getting any sort of feedback and being able to clarify instructions means a lot to me. I answer all e-mails (except for inquiries about selling space on my site for advertisements, and people wanting to exchange links whose sites have nothing to do with making science toys).
My e-mail address is:
science AT sciencetoymaker.org
replace the AT with @, no spaces. This is to elude spam bots, and it seems to work. I've had this address for a over a year--with thousands of e-mails--and no spam so far!
You can also reach me by telephone. I do not live in New York City, but it is the same time zone.
My mailing address is
209 Edler Rd
Williamsport, PA 17701
