The five young children at the center of the Netflix series Stranger Things were all born in 2002 or later, so, yeah, they don't know sh*t about Gak. Three of them tried out toys that you remember from being a person who actually lived through the 80s and 90s, and the results are frankly a shock to your creaky old bones. Eleven (known as Millie Bobby Brown IRL) doesn't even know what Pop Rocks are. Pop Rocks!
Sigh. This post-Millennial generation really has grown up entirely on iPhone games, hasn't it?
