Takeoff On a Conveyor Belt

If a plane sits on a conveyor belt whose speed matches that of the plane in the opposite direction, can the plane take off?

Yes, because a plane’s wheels roll freely and have no affect on the movement of the plane(unlike a car). The propeller or jet engine makes the plane move and the plane will be able to take off normally. If you don’t believe me, here’s proof.

First is Twice in Apple

My first is twice in apple but not once in tart.
My second is in liver but not in heart.
My third is in giant and also in ghost.
Whole I’m best, when I am roast.
What am I?

You are a pig.

How to Make the Great Escape

Shawn and Kyle are bunk mates in prison and are desperate to escape. There is an unbarred window high above them, but the walls are smooth and it’s too high for them to reach even when standing on each other’s shoulders. Their cell has no furnishings other than a toilet and even when standing on the toilet and each other’s shoulders, they can’t reach the window.

They’ve tried digging through the dirt floor but the wall extends 50 feet below. How could escape through the window?

Smurf imprisoned

They could dig down with their hands, but it would take too long to dig 50 feet down. Instead, they could pile the dirt they dig up to give them enough height to reach the window. If they put the toilet seat down, they could pile the dirt on top, then get on each other’s shoulders to reach the window. That would mean only one of them would be able to get out. The remaining prisoner could either continue piling dirt to account for the missing guy or the escaped prisoner could come back with a rope to help his mate escape.

Liquid Splashes But None Seeps Through

When liquid splashes me, none seeps through,
When I’m moved a lot, liquid I spew,
When I am hit, color I change,
And colors I come in, quite a range,
What I cover is quite complex,
Yet I am very easy to flex.

What am I?

Skin

A Big Rig Crossing a Bridge

An 18-wheeler is crossing a 4 kilometer bridge that can only support 10,000 kilograms and that’s exactly how much the rig weighs. Halfway across the bridge a 30 gram sparrow lands on the cab, but the bridge doesn’t collapse. Why not?

Since the bridge is 4 kilometers long, the halfway point would be 2 kilometers. The 18-wheeler would have used much more than 30g of fuel to drive 2 kilometers.
