Flying Saucer Science Experiment

Turn an ordinary plastic bag into an Unidentified Flying Object using the science of static electricity.

Flying Saucer Science Experiment

It’s a bird, it’s a plane, it’s a ... flying plastic bag! With this easy science experiment, you can make a basic produce bag levitate in the air while demonstrating the fascinating properties of static electricity. The secret lies in what’s called the “propulsion and repulsion” of electrostatic charges. Using a cotton towel, you can apply negative charges to both the bag and balloon. Like two ends of a magnet with the same charge, the balloon and bag will move away from each other, causing the bag to levitate.

Using the scissors, cut an inch-thick strip off the top (or open end) of the produce bag. You should now have a plastic loop or “belt.”

Rub the cotton towel over the surface of the balloon for about 45 seconds.

Laying the plastic loop on a flat surface, rub it with the cotton towel, again for about 45 seconds.

Have a partner hold the end of the balloon. Now hold the plastic loop roughly one foot directly above the balloon (like it’s a hat you’re putting on the balloon). Let go of the loop. The plastic should levitate in the air, repelled by the balloon’s negative charge.

The #1 Thing to Remember When Caring for a Sick Parent

It can help you be a better caregiver while also releasing you of overwhelming burden.

Caring for an ageing or sick parent at home can be a wonderful act of love — but it can also be a big sacrifice. Along with the new responsibility comes added stress to your life that's probably already taxing. Not to mention, it significantly changes the relationship between the two of you. If you're a caregiver for a parent, or thinking about what next step is best, this is one of the most important things to remember about this life phase. It can help you be a better caregiver while also releasing you of a lot of the burden that comes with the role.
