Citadel of Qaitbay

We just learned about the Windsor Castle.

Another ancient castle is the Citadel of Qaitbay, built in 1477 AD, in Alexandria, Egypt.

This castle was built in the same place as the Lighthouse of Alexandria, which was known as one of the seven wonders of the ancient world before it was destroyed around 100 years before this castle was built.

It is on the north side of Egypt, right on the Mediterranean Sea where it was a strong place to defend Egypt against any ships that might be coming to attack.

It is now a maritime museum, which is a kind of museum for ships and other seaside things.

Air Resistance

We just learned about Ballistics.

One part of ballistics is Air Resistance, which is also called drag.

When the rocket is flying through the air, it is pushing the air out of the way.
The shape of the rocket can make a big difference for how fast it can fly through the air.

If you think about it like pushing your hand through the water, if you point your hand it will go in the water fast.
But if you use the open flat part of your hand and smack the water, your hand will be more like a paddle and you'll slowly push the water out of the way.

We don't think about it much for air, but it works the same way for rockets trying to push through the air.
So the front of the rocket has to have a pointed shape for it to fly quickly.

Japanese Flying Squid

We just learned about the Opalescent Inshore Squid.

Another Japanese Flying Squid.

These squids live in the Pacific around Japan and Vietnam, and can grow to around 2 feet long.

They swim along by sucking water in on one side of their siphon, and then spitting it out the other side like a jet.

Sometimes they will swim so fast that they will shoot themselves up out of the water, and have been seen flying for almost 100 feet over the water!
