When you spin a fully expanded Hoberman Sphere, it rotates slowly. But if you collapse it mid-spin, the rotation speeds up dramatically. First we need to know that momentum measures how difficult it is to stop a moving object and it depends on the object's mass and velocity: ▪︎ Linear momentum refers to straight line motion (a tennis ball is easier to stop than a bowling ball). ▪︎ Angular momentum applies to spinning objects and depends on mass and angular velocity (a coin flip is easier to stop

⭐️🫁 BREATH of the WEEK: Hoberman Breath Bring your Hoberman sphere in front of your chest. Inhale slowly, expanding the Hoberman sphere to mimic your chest expanding with your deep breath. As you exhale slowly, make the Hoberman sphere smaller to mimic pushing the air from your lungs. Repeat this exercise a few times.
