Elaborate on the purpose of the rubber band.

What are the fun and practical USES of the ordinary rubber band? Here are all of them:

Keep food fresh - Seal a bag of chips, salad strips, or bread flour with a rubber band to keep it fresh.

Act as a reminder - Tie a rubber band to a special page of a document (you can also tie it to the cover to avoid wrinkles) or an elastic band is worn around your wrist to remind you to do something.

Rubber pad - Put a pair of rubber bands on the TV remote control or ashtray to avoid slipping or scratching the table.

Keep things together - like pencils or tape are index CARDS. This is obvious.

Bookmark - Wrap a rubber band around the front cover and the middle of the page you just read. The next time you open a book, the first page that isn't wrapped in a rubber band is the one you finished reading last time.

hair cord - maybe you can use it for a ponytail.

bundles of paper or poster - Roll up the paper or poster and wrap it with a rubber band for good storage.

Seat belt for the eye - Cut the rubber band open and tie two of them to the two eyeglass legs attached to the ear. If the rubber band is short enough, you can keep the glasses on your face.

Exercise your fingers - Put your fingers together through the rubber band, spread them out, and gather them together. Or, tie your index finger to your little finger with a rubber band and move your index finger away from the other fingers. Repeat the process with the other fingers.

Stress-relieving Rubber Band Balls - If made soft enough, the rubber band ball is the perfect pressure-relieving squeeze toy. You can use it to vent when you are upset.

Mark the volume of liquid in a colored solid container - Take a paint can as an example. Before you close the lid, wrap a rubber band around the outside of the can at the same level as the paint inside. The next time you need it, you'll know how much paint you have left at a glance.

Slingshot/Catapult - This is a toy that every kid loves to make out of rubber bands, but if you think it's hard to make a slingshot, I'm sure there are other practical ways to do it.

Simple art - Using a small nail board, draw rubber bands of different shapes and colors until all the pins have been used at least once. It's fun, creative and easy to do.

Bandage injured finger - when a finger is pricked or cut with cardboard, wrap a rubber band around the injured finger until the wound heals.

Pencil eraser - Fold the rubber band in half a few times. It is very useful to use it to erase pencil marks.

Let it wait for a while to form a ball. Repeat every few days as necessary.

Keep peeled apples fresh - This one seems strange, but I've tried it and it works really well. Peel and cut the apples into wedges. Gather all the apple pieces together and wrap them in a clean rubber band so that the apple feels like a whole again. This slows the Browning time by 50% compared to just putting the apple in a sandwich bag.
