how do I germinate a baobab

[gallum90]

as the tital implies I acuired some baobab seeds and was wondering how to germinate them I did alot of reading on their growth paterns and found they sprout up really fast and grow to a workable condition pretty quickly (well as far as trees go...) but idk how to germinate them and I don't want to mess them up

and another question is is how long can a baobab tree seed survive with out being planted? I am just wondering if I can save a few of them for later on in life.
