Steps
Trace and Seal
  • Place the zip bag on top of the stencil and trace the shape with a marker.

  • Adjust the heat sealer level to the lowest point.

  • Place the zip bag on the sealer. Adjust the position to make sure that the crosses/dots are on the sealing line.

  • Push the sealing arm down and keep the arm down for 3-4 seconds.The zip bag must be straight to avoid any wrinkles from sealing.

  • Tape a narrow paper on the zip bag to make a gap in the middle of the sealing.

  • Place the zip bag and push the sealing arm down.

Make a Hole

  • Apply double-sided tape on the bottom of a connector. Make a through hole with an awl.

  • Cover the hole on the other side with tape.

  • What if you make a pouch with different sizes/shapes/diagonal lines/circular shape? 

  • What would happen if this is attached to other materials such as paper? 

  • What would happen if you insert other materials such as liquid, color?

  • Different thickness of transparent film? 

  • Can you create a biomimicry soft robot?
