Design and build the strongest bridge you can that spans at least 1.5ft with materials around your house (craft supplies, building toys, newspapers). Get creative with materials!
What makes a bridge strong? What features bring stability to bridges? Shapes? What materials do you have around the house that you could make your bridge out of?
Build your bridge! How can you combine/attach materials? Test your bridge. What modifications can you make? Bonus Challenge: Can something travel over it? A toy car? A remote-controlled car?
Film a short (max 2 min) video pitch of your invention. Include details like who is it for, what problem does it solve, etc. Have fun! Upload/share your video to twitter, facebook or Instagram. Don't forget to tag us!
