Phyphox is an app that allows you to use the sensors in your phone for your experiments. This video will show you how to calibrate and use the audio amplitude sensor in the Phyphox app, so you can measure sound levels of noises around you. Written instructions for projects or lesson plans that you can do with a sensor app are available on the Science Buddies website at https://www.sciencebuddies.org/science-fair-projects/science-projects?s=sensor+app&ytid=3cpZEVSC6Nw&ytsrc=description and…
This is a new and improved version of our ion wind rotor project! Watch the original video here: https://youtu.be/SYJP36RJKPA. That version works well as a quick demonstration. This version requires more tools and materials, but works better for a science project. Written instructions and suggestions for a science project are available on the Science Buddies website:…
This is the prototype RGB LED Time Fountain I designed and built. It uses RGB LED strip lights to strobe a stream of water drops to make them appear as if they are levitating. By strobing the different colours out of phase with each other some incredible effects can be created.
An Arduino Uno controls the timing of the RGB strobe and the PWM of the pump. Bluetooth communication was achieved using an HC-05 Bluetooth module and the "Arduino bluetooth controller" app by "Giumig Apps".
The code…
This video shows how to build an ion wind rotor with a Van de Graaff generator. This is a good demonstration to show the working principles of an ion thruster. Written instructions are available on the Science Buddies website: https://www.sciencebuddies.org/stem-activities/ion-wind-rotor?ytid=SYJP36RJKPA&ytsrc=description

You probably know that light travels in straight lines. So, how can you guide a light beam through a maze and around obstacles to a target? You can use mirrors to do that! As light bounces off of reflective surfaces, you can redirect a light beam to wherever you need to if you place the mirrors correctly. Can you solve the mirror maze challenge shown in this video? Written instructions as well as free maze and target templates are available on our website at…
How can you use sun paper, also called nature print paper or photosensitive paper, for a science project? Check out our website for written instructions and to learn what this project has to do with the process for making microchips: https://www.sciencebuddies.org/science-fair-projects/project-ideas/Phys_p127/physics/sun-print-best-time?ytid=0QQAU5gB0fI&ytsrc=description

Is this water "falling up"? This video explains the illusion behind the stroboscopic effect and how it can make water drops look like they are falling up or even hovering in mid-air. Watch this video to learn how to build your own levitating water fountain: https://youtu.be/6vWprI6OPJo, and this video to learn how to build your own brighter strobe light using an Arduino and an LED strip: https://youtu.be/JkEsGXmInKo. Check out the Science Buddies website for written instructions:…
Have you ever seen a video where it looked like a car's wheels or a helicopter's blades were spinning backwards? This optical illusion is called the wagon wheel effect, named after old movies where it looked like wagon wheels were spinning backwards. This video explains what the wagon wheel effect is and how you can film it yourself at home with a fan or a drill. Written instructions for this fun STEM activity are available on the Science Buddies website:…
