How to make it

1
Draw a battery shape on cardboard: a wide rectangle with a small bump on one end. Cut it out.
2
Outline it in thick black marker. Draw a thin red bar at the left edge, to show the last bit of charge.
3
Write “1%” in the middle in big numbers.
4
Add rope shoulder straps through two holes.
5
Tape or tie a long white cord to the bump, and hold the plug in your hand.

Make it better

Look for a plug socket every few minutes.
Say “I'm on low power mode” to anyone who asks you to dance.
