Animals vs Engineers



Welcome back to Camp CrunchLabs! Today, we’re learning about nature’s greatest engineers… animals! But will Zach King try to steal my new monkey friend? It’s not too late to join us for your least boring Summer ever!

Each build-it-yourself STEM toy teaches the magic and fun of engineering principles and includes exclusive weekly videos like this one that accelerate your learning! Ready for Camp? Visit for more info.

A big thanks to our special guest​⁠ @ZachKing for joining me!

This Summer’s Challenges:

First, a RUBE GOLDBERG MACHINE, but somewhere, it has to include WATER. A Rube Goldberg machine is basically a chain reaction you build, usually to accomplish a simple task, like turning on a light or feeding the dog. This summer, part of the chain reaction has to include water.

Next up is a SLO-MO VIDEO, but this one has to include one of the most important engineering devices ever invented… GOOGLY EYES. Now, for the record, they don’t need to be official googly eyes with a lens – cutting out two white circles, and smaller black ones, will totally get the job done.

The final option, and again, you can totally do as many of these challenges as you want, is a REVERSE-VIDEO USING FOOD. There are a bunch of free phone apps that let you shoot a video and then play it back in reverse, so the challenge is to create something that looks cool in reverse and incorporates food in some way.

  1. Buena noche Señor Mark.
    Reciba usted un cordial saludo. Le escribo desde Yopal -Colombia 🇨🇴. Mi hijo Ian Alexander, tiene 7 años y no se pierde un video suyo, le parecen muy interesantes todos sus juguetes de ingeniería. El quiere ser un ingeniero como usted, lo admira mucho. Es tanto así que quiere conocerlo algún día y poder estrechar su mano.Ya está ahorrando para poder viajar a su país y poder saludarlo.
    Yo como su madre quiero darle gracias por hacer videos sanos y muy interesantes para que los niños descubran que aptitudes tienen para lograr desempeñarse en lo que a ellos les guste.
    Atentamente, Yesenia Delgado. Bendiciones 🤗🫂🇨🇴
