Cloud Forming Apparatus Glass Rubber 9.5" H Earth Science Classroom Model Case of 20 by GSC International

This cloud forming apparatus is designed to demonstrate the principles of cloud formation in a classroom or laboratory setting. When atmospheric pressure is lowered inside the glass chamber and smoke particles are introduced, a nucleus for water droplet formation is created. Compressing and releasing the rubber bulb produces a visible cloud inside the flask, helping students observe condensation and pressure changes in real time. Ideal for earth science and physics instruction, this apparatus supports hands on STEM learning. Each unit is made from glass and rubber for repeated use. Product dimensions are approximately 4.25 inches long x 8.75 inches wide x 9.5 inches high. Sold in a case of 20 with instructions included.
