The Backyard Scientist creates a video about testing out three "dangerous" toys from the 1960s: the Water Wiggle, Swing Wing, and Hop Rod motorized pogo stick. He starts by examining the Water Wiggle and Swing Wing but quickly moves on to the Hop Rod, which he has been trying to acquire for some time. After finally getting his hands on a real Hop Rod, he tests it out, experiencing some painful injuries in the process. He also tries out different fuels to see which one works best and eventually settles on naphtha. The video ends with the scientist reflecting on why toys from the 1960s are often so hazardous and promoting a sponsor, HelloFresh.
