My grandma recently got a walker and she hates how difficult it is to turn sideways. I've seen other elderly people with tennis balls on their walkers, and assumed that this was the solution. It is :)
Step 1: Materials
You'll need a box cutter, a tennis ball, and something to hold the tennis ball in place (I used my vise). Optional: A hammer and a nail to poke a hole before cutting with the box cutter.
Step 2: Secure the Ball
Secure the tennis ball so that it doesn't move around when you're cutting it.
Step 3: Hammer Time
Hammer the nail into the ball until you hear the air hiss out of the ball.
Step 4: Remove the Nail
Take the nail out of the ball.
Step 5: Cut the Ball
Cut a line starting at the hole. The size of this line will depend on the size of the walker's legs. I cut a line about 2 inches in length.
Step 6: Make an X
Cut another line to make an X shape.
Step 7: X Cut
This is what it should look like.
Step 8: Put the Ball on the Walker's Legs
Push the ball onto the walker's legs, pull back so that the flaps open up, and push it back in so that it is secure.
Step 9: Done
