What is this text mainly about?

You probably know sharks have very sharp teeth, but did you know they never run out of them? If a shark loses a tooth, another moves forward from within the shark’s jaw, where it keeps a nearly unlimited supply of replacement teeth. This way, it’s almost impossible for a shark to end up without a full set of teeth. This is a phenomenon unique to the shark. No other animal in the world has teeth quite like the shark’s. A shark can go through as many as 20,000 teeth in its lifetime!

• Sharks have large jaws.

• Sharks hibernate during the winter.

• Sharks have sharp teeth.

• Sharks never run out of teeth.

Ideas That Pop

Inventing is not just for adults. Kids from across the country recently showed off their great ideas. They took part in a contest to create a new use for Bubble Wrap. Bubble Wrap is a packing material that has air-filled plastic bubbles. It is used to protect objects that are breakable.

Andy Boler, age 10, from Texas, used Bubble Wrap to make a cover for plants. It protects plants from the cold. “I like building things that could help people,” he says.

Other inventions in the contest included a kite-making kit and a wrist cushion. Some of the kids’ inventions may be turned into real products.

“We have very few rules,” says a contest spokesperson. “One of the main goals is to get young students thinking.”

• A kite making kit is an invention.

• Inventing is not just for adults.

• Kids can be inventors too.
