Watch ANDRILL scientists examine a sediment core, find out about new developments, and discover ancient diatoms (single-celled marine organisms).

00:23:36
How do ANDRILL scientists drill and retrieve sediment cores from under the ice and sea, and why do they do it?

00:31:34
Join us for an overview of the ANDRILL (ANtarctic geological DRILLing) Project, a multinational collaboration among 200-plus scientists, students, and educators from five nations, to recover sediment cores (layered sections of earth) from under the Antarctic ice and seas.

Join us as we talk with Dr. William Fry, emeritus professor at Stanford University and the father of gelotology, the study of humor and laughter, and their effects on the human body.

The Exploratorium's Ron Hipschman shows how a double disk with a string attached is a great way to study the physics of motion. Then Captain Yo and Doc Popular astound with amazing yo-yo tricks.

Ezra Daly explains how he makes musical instruments out of car and motorcycle parts, then plays his Frankenbass, created from a Moto Guzzi motorcycle gas tank, a chrome tailpipe, and scrap mahogany. Next, Doc Popular (aka Brian Roberts) shows how he creates instruments by circuit-bending toys. Doc--not just an inventor and a video editor but a yo-yo champion as well--will also demonstrate some yo-yo tricks.

Inventors Windell Oskay and Lenore Edman demonstrate the CandyFab 4000, a printer that creates 3D sculpture by stacking 2D images made of sugar. Drawing from disciplines as varied as circuit hacking and sewing, the sugar printer is only one of Oskay and Edman's many projects, which include an interactive dining table and hard-drive wind chimes.

While demonstrating how to build an electromechanical digital clock, Jim Newton talks about different kinds of tools—from low-tech, such as a drill press or a welder, to high-tech, such as laser and plasma cutters. Jim is a lifetime maker, veteran BattleBots builder, and former MythBuster.
