TX-12 - Electric STEM KIT - Suspended Blow Ball

Suspended Blow Ball (TX-12) ⭐⭐⭐ · ~25 min

⚡ Principle Based on Bernoulli's Principle: fast-moving air creates a zone of low pressure. Higher atmospheric pressure around the stream pushes the ball back into the center, keeping it suspended.

🔩 Parts

Wooden boards (turbine casing)

Motor ×1 

Fan blade ×1

Pulley ×1

20mm foam ball x1

Battery holder with knife switch x1

Screws & cap screws x1

📋 Steps

Assemble the outer casing of the turbine as shown in the picture.

Pass the screw through board No. 1 to tighten the pulley, then install the fan blade.

Fix the motor with screws, then install the battery holder and the fan assembly.

Assemble the base and the side board, then finally secure the battery holder with screws.

⚡ Fun Fact! This is the same principle that allows massive airplanes weighing hundreds of tons to stay in the sky!

💚 Tip If the ball falls to the side, check the alignment of the fan in Step 2. The air stream must be perfectly vertical.
