I have been buying things from …
I have been buying things from Scientifics since the 50's. I still have a catalogue from that time. It may be me but it seems that what you have to offer, as time goes by, is more like toys to entertain than learning scientific principles. I buy a lot of "Rattle-back-space pets." I like to pass these out to people, especially young people, asking that parents don't show kids how they work but letting the young play with it and "discover" how it works! If you show them how it works they will bore quickly, but discovery may drive their curiosity. Also your web address gives them a place to go to learn more. I wish you had instructions on the principles that make them spin and why it changes direction because I don't know. I would like to see a price break for buying large amounts so I can pass out more of them. It's like free advertising for you. A little help! Also there are diagrams for tying knots, but I would like to see a booklet that shows/tells what applications a knot is used/good for.
