Getting any sort of feedback and being able to clarify instructions that are un-clear really 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).
When you e-mail me please put "science" in the subject line or I might accidentally mistake it for spam. If you do not hear back from me try again. Occasionally when I reply I get a message that my reply cannot be delivered. It has only happened a couple of times, but if you don't get a reply try sending through some other e-mail account.
My e-mail address is: science AT sciencetoymaker.org replace the AT with @, no spaces. This is to elude spam bots.
You can also reach me at home evenings (eastern standard, New York time) (570) 321-7468 If I am not home, please do not expect me to call back long distance, as I do not have free long-distance calling. Just call back. My mailing address is
