752123 Break the Board Demonstration Kit
New! Break the Board Demonstration Kit What happens when a sharp, downward force is applied to the end of a paint stirrer hanging from a table while its other end is covered by newsprint? Do the objects fly off the table? Does the newsprint rip? Do the objects not move? Challenge your students’ prior knowledge about forces, surface area, and air pressure with this easy-to-perform demonstration. Contains enough materials for 2 practice runs and 10 demonstrations. Includes instructions.

752904 Bottle and Card Demonstration Kit
New! Bottle and Card Demonstration Kit Flood the classroom with discussions about surface tension, air pressure, and adhesion as students explain why a card “sticks” to the opening of an inverted jar of water and why the water does not spill out when the card is removed. Chal- lenge students’ observational and critical-thinking skills with this classic discrep- ant event. Kit materials may be used indefinitely. Includes instructions.

754625 Disappearing Test Tube Demonstration Kit (above); in use (inset)
New! Disappearing Test Tube Demonstration Kit Amaze students with a discrepant event using cooking oil and glass. A test tube immersed in cooking oil seemingly disappears as the tube is filled with cooking oil. Introduce scientific observation, properties of light, reflection, and refraction as students try to explain this modern-day “cloaking device.” Kit materials may be used to perform the demonstration multiple times. Includes instructions.

Magic? Anti-gravity? No. Strong repelling magnets. Position the metal tip against the glass, then spin the axle. The small friction point between the tip and glass helps the floating axle rotate for several minutes. Stimulate conversations about forces, perpetual motion, magnetism, or mechanics. For an amazing light and optics demo, use a stroboscope to make the axle’s rotational direction appear to go in reverse. Assembled size (with glass), 51
