How does a regular 15-year-old named Russell Horning turn into Backpack Kid, the dance sensation with 1M+ Instagram followers? It helps if you have a signature style (stiff, swinging arms), a signature look (t-shirt and backpack), and a signature stare (cold). It also helps if Katy Perry has you join her on the season finale of SNL after seeing your Instagram videos. That appearance brought him a lot of new attention, but Backpack Kid was already trending upward on his @thebackpackkid Instagram account, getting a shout-out from Rihanna, who reposted a video of his to celebrate her Grammy nominations. Look for Backpack Kid to continue to pop up in hip-hop videos, like Ayo & Teo’s “Rolex,” while still entertaining his fans with antics like dancing with random groceries in the supermarket.
