Fidget Spinner
Objective: Make fidget spinners and compare the types of fidget spinners and determine which one spins longer and why it does spin longer.
Materials:
Cardboard sheets
Foam sheets
Bamboo skewer
Metal washer, small
Glue.
BASIC FIDGET SPINNER DESIGN:
Cut out the design of your choice from the fidget spinner template Design
Choose a fidget spinner body from the materials provided. Trace the design onto the chosen materials, cut it out using scissors
Use a paperclip to poke a hole in the center of the spinner.
Widen the hole using the sharp end of the bamboo skewer. The hole should slightly be larger than the diameter of the skewer.
Using scissors, carefully score and break a 1.5 to 2cm piece of the bamboo skewer to use as the spinner bearing.
Use sandpaper to smooth the cut ends if the bamboo skewer.
Insert the piece of skewer through the hole in your spinner.
Hold the skewer between your thumb and index finger so the spinner is vertical. Use your other hand to flick the spinner.
Weights may be affixed to the arms of the spinner using tape or glue.
Two circular pieces of cardboard or foam can be placed on each side of the spinner body to prevent the body from moving while in motion; these can also be considered "finger grips".
EXPERIMENTS:
Fidget spinners are based on the concept of angular momentum. The mass and the velocity of an object determine how much distance it covers but, in this case, we want to know how long it spins for not how far it goes.
I set up an experiment with two handmade fidget spinners of different masses and gave them a spin with equal velocities and it turned out that the spinner with more mass spun longer than the other one with less mass.
