A few years ago a bunch of our grandkids had devices similar to that launcher in the picture.
It is a hysterical toy - every grandkid had a different approach - run and pounce on the launcher, and depending on the angle, watch how high (or not) the ‘missile’ went.
I say hysterical because we laughed constantly at the results.
I think I may still have an unopened one around here somewhere - - - thought we might re-vive the toy some day!
