Do Satellites Collide?

27 March 2013
Presented by Chris Smith, Redi Tlhabi.

Do satellites collide? Can albinism be diagnosed on a scan? What causes the timing of the equinox to vary? Do bullets fired in the air still kill people? Can we make a human from just a genetic code? Why doesn't glue stick to the container? What's left underground once oil has been removed? And why can't we tickle ourselves? Join Dr Chris for another round up of the best science questions from South Africa.
