Frostbite Theater

Announcer: Frostbite Theater presents... Cold Cuts! No baloney!

Joanna and Steve: Just science!

Joanna: Hi! I'm Joanna!

Steve: And I'm Steve!

Water: Splash!

Steve: Man...

Joanna: On April 1st, we showed you that, if you're careful enough, you can keep water in an upside-down container without a cover.

Steve: Come on...

Water: Splash!

Steve: No! Argh!

Joanna: Well, that was a lie.

Steve: What!?

Joanna: The problem is that the opening is just too large for surface tension to do the trick. What we need to do is divide the large opening into a bunch of smaller openings!

We'll do that by covering the opening with a piece of screen mesh.

Apply some hot glue to the jar's rim and smash it onto the screen while the glue is still warm.

Trim the excess off with a knife and you're done!

Now, the surface tension across the individual openings is enough to keep the water from coming out!

Water: Splash!

Joanna: Thanks for watching! I hope you'll join us again soon for another experiment!

Steve: You fooled me and, you made me wet my pants...

Joanna: Well, it was April 1st. What were you expecting?

Bazinga!
