The "Cool Stuff" Buzzing Magnets (often sold in sets of 2) are high-powered, polished hematite magnets with an distinctive ellipsoidal or oval shape. They are designed to create a loud buzzing or chirping sound when tossed into the air, as the two magnets attempt to come together.

• Powerful Material: Made from, shiny, black, polished hematite.
• Shape & Size: Oval-shaped ("Snake Eggs") measuring approximately 4.5cm up to 6cm in length.

• Age Restriction: Generally recommended for ages 8 and up. 

How to Use:

1. Hold both magnets in one hand, slightly separated by your thumb and fingers.
2. Gently throw or toss them into the air.
3. As the magnets collide and vibrate in mid-air, they produce a rattling "buzz" sound. 

Safety Warnings:

• Not Indestructible: The magnets can chip or break if they hit hard surfaces like concrete or wood floors.
