Finger Puppet

Watch the video below for step-by-step instruction to assemble the circuits to make your Finger Puppet!


Hi guys….

We’re going to make Finger Puppets in our project today. They’re no ordinary puppets…Their noses can "blink" like Rudolph the red nose reindeer… So what are you waiting for? Let’s make them together 🙂


Please follow the step-by-step instruction in the video above to make your puppets.


Are their noses blinking when you squeeze your finger against the puppet’s body?

That’s really cool….


Do you want to know how it works? Let’s explore it together 🙂


Do you remember when you assemble your puppet; you had a battery and an LED or a tiny lightbulb?

Battery gives energy to the tiny lightbulb so that it has power to light up. As you know batteries are uses practically everywhere around us. For example they are used to power cellphones, your toys, flash lights, remote controls, cars, and many many more.

Can you think of another good example?





When the tiny lightbulb is connected to a battery, it lights up. But you need to make sure that they are connected correctly. Make sure the + and the – ends of the battery are connected to the + and – ends of the lightbulbs, so that it forms a loop or a complete circuit like shown in the diagram.





But when the loop is broken, the light will turn off.

When the battery is not fully connected to the LED, the circuit is broken, and the electrons cannot find their way back to the battery. This is called an open circuit.

Because electrons cannot find their way back to the battery, current is not flowing through the circuit, and that’s why the LED is off.








This is what happens in your finger puppet!  



Do you notice that before squeezing the wire to the puppet’s body, the nose didn’t light up? That’s because the loop/circuit is broken so electrons have no way to reach the lightbulb. When you press the wire against the puppet’s body, the loop is not broken anymore! You’re forming a complete circuit so electrons have a pathway to reach the lightbulb. And that’s why the light will turn on 🙂
