Bubblebot

INVENT A BOT THAT CREATES BIG, BEAUTIFUL BUBBLES using only a few Bits and some items from around the house. Slowly move the slide dimmer to control how quickly the bubble grows. Can you make the ultimate bubble?

 

These instructions correspond to the Gizmos & Gadgets Kit: 2nd Edition. If you have the first edition of the Gizmos & Gadgets Kit, please refer to those instructions. They can be found here.

 

HOW IT WORKS:

  • The p1 power Bit sends a signal through the circuit.
  • The i5 slide dimmer controls how much signal moves through to the bargraph and fan. 
  • More LEDs on the o9 bargraph light up as more signal passes through. 

 

When you're done building your invention, keep the fun going by following the Invention Cycle below!

 

PLAY: Become a master bubble-crafter! Can you release the bubble from the tube so it floats through the air? 

 

REMIX: What changes can you make to your invention to create even bigger bubbles?

  • MODIFY THE BUBBLE TUBE. Cut a fringe into the edge of the bubble tube. This helps it hold more bubble solution. 
  • TRY DIFFERENT CONTAINERS for blowing bubbles. Replace the paper bubble tube with plastic bottles you find around the house. Explore whether a yogurt cup works better than a milk carton!
  • SWITCH IT UP. Which other Bits can you use to control the Bubblebot?
