Haven't seen a discussion thread specifically for the ISS so i decided to make one.
Looks like the crew of the ISS are having alot of fun.
At first i thought it was kind of weird to spend cargo mass on stuff like decoration and 'fun' things in general, but if you think about it, most souvenirs don't weigh much more than a few grams, so if you need to pay $10,000 for a kg for example, you only need to pay less than $100-500 for a cheap darth vader mask and lightsaber to the ISS. not much compared to the rest of the gear on the ISS. Plastic toys can also be reused for years, so they don't have to launch it up there every year, only once.
Does the ISS have a 'special junk' bag?
