I'm Deysi from Design Squad, and I'm with: Sorry.

We are going to repurpose this vacuum cleaner.

ELLIOT: "Repurpose" means using an item the way it was not designed to be used.

(vacuum starts) Normally, this is used in your everyday life... to suck up unwanted dirt.

ELLIOT: If you're going to do some activities with a vacuum cleaner, like we are, you should always have an adult present.

That's pretty cool.

I love how like each ribbon goes at a different time.

This vacuum is a fan inside a box.

ELEANOR: The fan is pushing the air in this direction.

So then the air collects the dirt.

We're going to repurpose it and switch the hose around from here to here, so it therefore blows air out.

DAVID: I think not all vacuum cleaners actually do this, so check with your vacuum cleaner.

Instead of the vacuum creating suction, it's blowing air.

We're going to use the blowing capabilit of our vacuum cleaner... and make an air hockey table.

Eleanor and David are using cardboard, a plastic bag and some tape.

It's a proof-of-concept of an air hockey table.

ELLIOT: "Proof-of-concept" is testing the idea.

DAVID: It's just a small part of it, so we can actually see if the bag system actually works.

Oh!

We can feel some air coming out.

The top is curving.

The cardboard is curving because the bag is curving.

DAVID: Why don't we just try a big box.

Eliminate the bag altogether.

We have this big, nice bike box.

We're going to make this whole thing our air hockey table.

I think we need to seal it up really good and tape it.

It should be air tight.

ELEANOR: This bike box has double-thickness cardboard.

We hope it's going to work better because it maybe won't curve.

Let's try one inch apart for each hole.

ELLIOT: We're going to put the vacuum right in here, and that will supply air to the table.

(vacuum starts) There we go.

Oh, look!

You see how the big puck floats and the little one doesn't?

ELEANOR: A big puck works much better than a small puck because it has more places that the air can push it up.

DEYSI: The puck is really floating.

It's actually working!

ELLIOT: We have repurposed the vacuum cleaner!
