This is an odd idea:
For $2 you can send a something measuring 0.4 x 0.4 inches (that is 1 cm x 1 cm, pretty small) to space. Aren't you excited about it? Hello? Anybody there?
Anyway, it's only $2, so it's not that it's a huge investment for something so meaningless. People spend more meaningless money out there, like paying to send small digital gifts to people on Facebook, or paying taxes so that companies that make bad decisions in what to invest can get out of it for free... I could make this a long list, but I won't bore you with my list. Just think about last month's expenses and all the things that you could have lived without. I'll assure it's way more than $2.
