Well I know of coral castle , and I read his book on magnetism as a kid but was to young to make sense of it . Maybe I should go back now that it's been probably 30 years and take another look. Or you could also just blow my mind too. Edit ( ok I just noticed the link , have you tried it? I cracked water as a kid but with DC so this would be pretty damn cool. Got anymore cool stuff to share?
