Greetings Voretx-l Lefthanded as well as righthanded molecules respond to gravity differently: http://www.theavalonfoundation.org/docs/acc-quartz.html
The http://www.theavalonfoundation.org has other gravity chiral material interactions studies..dextrose and L-tartaric acid. Sad that most studies on chiral materials are done for their drug interactions.
