We had Jungle Jim visit our library yesterday for his Mousetrap Science Show. We had a good crowd of about 40 children, and they were very enthusiastic and seemed to be having a great time. Jungle Jim's silly jokes and use of audience participation was spot on. He invited at least 15 children onstage during the show, and everyone got to say and do actions with him as he performed.
He made a number of simple machines out of balloon animals and children (mostly who stepped down from the stage with static-y hair), and effectively explained how each machine works and why it might be important in our lives. He then took all of the machines he had made and applied them by creating a Rube Goldbeg-esque mousetrap to catch a mouse. Fun warning to librarians- Jungle Jim may ask for your participation as well, which my patrons enjoyed immensely.
Overall, Jungle Jim's show was extremely successful, and I will certainly have him back in the future. His prices are toward the higher end, but it was worth the money.
