This creature that mysteriously climbs up and up as you alternately pull the strings down is one of the first science toys I set to figuring out as a kid. The only problem was that it was cut and drilled from wood--too hard for kids to make. So I have developed an easy-to-make version that uses thin cardboard and straws that even young elementary students can make with a little help.
