smart suspension bridge

by Vihaan Raman

Published on November 22, 2017

we have created a mart suspension bridge with the help of little bits circuits that produces a loud beeping sound when the bridge has a lot of load. we were inspired by this idea based on a school stem project.


Duration: 1 hour

How To Make It

STEP 1 : Building the Bridge!

We first took a cardboard sheet and cut it accordingly. after we used Popsicle sticks and stuck around the edge with the help of some glue. After you have stuck the Popsicle sticks around the edge, take toilet paper rolls and stick them along the sides so that they look like pillars.Coming back to Popsicle sticks, take 2 Popsicle sticks for each toilet paper roll and stick them from the inside of the rolls. The ribbon is used to look like suspensions. Attach them from one Popsicle stick to the other.To make the bridge look attractive, add some color using paint!

STEP 2 : Does it work?

Now that your bridge is ready, using little bits create a quick circuit and tape it to the bottom of the bridge. Now your bridge is ready! But wait!!! Does your bridge work? Lets find out..... Using Toy cars start placing one car and increase the number every time till you hear a beeping sound. When you hear this Beeping sound, you will see that your bridge is too heavy
