Why are e-Books better than regular paper books?

E-Books are cheaper than paper books and you can build a whole library of our digital fun science experiment books.
Instantly available worldwide – just download the eBook, read it on screen or print it out instead of waiting for ‘snail mail’. Our science experiment e-books take only a minutes or two to download.
E-books are very convenient. You can download your science experiment e-book onto a portable reading device before you start with an experiment that requires you to be mobile, or just print out the entire book or only the section you require.
