YC S27's ScamMyGrandparents.com lets you simulate these against your own grandparents, so you can shame and educate them when they naively wire your college trust fund to a safe account. You are able to refund either the whole amount, or keep some for yourself since they won't know any better. The cost of service is variable depending on how many homes they own.
