My son was asking for this book for some time and I finally got for him as one of his Christmas gifts. The book consumed him for hours. Very informative, well written and easy to understand for young minds. Photos are amazing

I don't know much about this product except that it worked very well at the time I needed it; and there were no harsh after effects - meaning - no rashes, no allergic reactions, no problems whatsoever. Good pricing, great delivery.

There is not another glue in the world that can touch this. I've used it anywhere from gluing my shoes back together, using it to repair a broken graphite spar on a wheelchair. You can glue just about anything to anything else. Be careful using it, if it gets on bare skin then wipe off with a wet paper towel,which you can also use to wipe up any glue that squeezes out of your project. It expands to 3x while drying.
