How to Materially Innovate

Indoor Solo Tennis

During these times of confinement (like we are living in Barcelona) and living in an apartment building, you need to find innovative ways to have fun and stay in shape!

Ingredients:

  • Tennis ball
  • Plastic pin (about 3 inches long)
  • A (very) long rubber band (about 10 feet)
  • A weight (such as a heavy paper weight) or a fixture on the floor
  • A tennis racket or paddle
  • Some space (optional)

Instructions

  1. Carefully pass the pin between the tennis ball over and the plastic just beneath it , leaving part of the in out in its middle part (this is a bit tricky - see photos)
  2. Tie one end of the rubber band to the pin on the ball
  3. Tie the other end to the weight of floor fixture
  4. Hit the ball with the racket or paddle and wait for it to come back. Warning: the harder you hit it, the faster it will come back to you
  5. Have a ball!
