Cardboard Grabber!

Activity Eight


What can we as engineers make with everyday materials?

Let’s create a simple grabber that can extend and grab something!

By the end of this activity, and some parental assistance, you will have a fun tool to help fetch things from afar!


In the activity, you will construct a grabber out of cardboard.

How far can it extend? Will longer cardboard strips help? What can be used to help grab with it?

  • Toothpicks
  • Scissors
