The oval-shaped nuts are typically 12-by-10-inches wide. 
Once the nuts are ashore, the mesocarp also aids in the aboveground germination process by collecting rainwater; in addition, the endosperm has in its milk a provision for seedling establishment Exactly how far the seeds blow will depend on the strength of your fan but you should definitely see a difference in the horizontal distance traveled between a "plain" seed and one with a dispersal mechanism.
