Tongue Depressor - Wood

Wooden tongue depressors are disposable wooden sticks with smoothed, rounded ends designed for oral and throat examinations measuring 15cm. These non-sterile, single-use, non-toxic tools help medical professionals, such as doctors, nurses, and ENT specialists, hold down the tongue to view the pharynx clearly. Sold in packs of 100.  

Wooden tongue depressors are widely used as disposable mixing sticks for acrylics and mouldable silicones. They are considered a staple in crafting, moulding, and casting due to their low cost and high tensile strength.

Wooden tongue depressors (often called "craft sticks") are staple materials for school experiments due to their uniform size, low cost, and ability to store elastic potential energy.

Key Features and Uses:

• Dimensions: 150mm x 16mm
• Material: Generally made from high-quality, splinter-free wood like Northern White Birch.
• Safety: Non-toxic, single-use, and designed for hygienic disposal to prevent cross-infection.
• Applications: Essential for medical clinics and hospitals, while also widely used for craft projects, waxing by beauty therapists, and by tattooists.
• Safety Precaution: Non-sterile, so they should not be used for sterile procedures

Physics & Energy Experiments

• Popsicle Stick Chain Reaction: Interweave sticks in a "cobra weave" pattern to store elastic potential energy. When the end is released, the tension converts to kinetic energy, causing the sticks to "explode" into the air in a cascading reaction.
• Catapult Construction: Use a stack of sticks as a fulcrum and a single stick as a lever arm. This demonstrates Newton's Laws of Motion, force, and trajectory by launching lightweight objects like pom-poms.
• Sound Harmonica: Sandwich a wide rubber band and small straw pieces between two tongue depressors. Blowing through the gap causes the rubber band to vibrate, illustrating how sound waves and vibrations are created. 

Engineering & Structural Challenges

• Bridge Building: Students design bridges to test weight-bearing capacity and structural integrity. It introduces concepts like trusses (triangular supports) and how different geometric shapes distribute load.
• Tower Stability: Use sticks and adhesives to build the tallest freestanding tower possible. This teaches students about base design, center of gravity, and material efficiency.
• da Vinci Bridge: A specialized engineering challenge where sticks are assembled into a self-supporting arch without glue or tape, relying entirely on tension and friction. 

Biology & Math Applications

• Pollination Simulation: Attach felt or cotton to a stick to represent a "bee". Students use the stick to move "pollen" (like crushed cheese puffs) between paper flowers to visualize the pollination process.
• Math Visual Aids: Use sticks for hands-on learning of fractions (breaking sticks into parts), place value (bundling sticks in groups of 10), and geometry (forming polygons to study angles).
• Measurement: Younger students can use tongue depressors as non-standard units of measurement to compare the lengths of various classroom objects.
