Join Suzie as she brings physics down to earth, and explains how scientists can walk into a lab and discover ground-breaking things about our universe. She uses stories, demonstrations, and a bit of Ri history, to explore how physics experiments have impacted our lives. From the discovery of X-Rays, to the history of women in physics, to the race to split open the atomic nucleus.

This talk was recorded at the Royal Institution on 3 May 2022.

Suzie Sheehy is a physicist, academic and science communicator who divides her time between her research groups at the University of Oxford (where she is a Royal Society University Research Fellow) and the University of Melbourne (where she is Senior Lecturer). Her research focuses on developing new particle accelerators for future applications in areas such as medicine and energy.

An award-winning public speaker, presenter and science communicator, Suzie is dedicated to sharing science beyond the academic community. She has delivered professional lectures and keynote presentations, written and delivered live shows to tens of thousands of students, is an expert TV presenter of Impossible Engineering for Discovery Channel and in 2018 delivered her first TED talk as part of TEDx Sydney, which has received over 1.4M views.

In this weather science experiment, we walk through how to make a fire tornado. Using isopropyl alcohol, a wire trashcan, a ceramic bowl, and a Lazy Susan, we see how air movement affects fire! To use this weather experiment for a science fair project, consider questions like: How fast does the air need to be moving to create a fire tornado? What is the impact of the wire trashcan on a fire tornado?

❗️ SAFETY NOTE: Due to the nature of this experiment, it is best performed in a lab with a scientist or science educator.

▶️ Get supplies to make your own fire tornado:
http://www.beardedscienceguy.c....om/how-to-make-a-fir

▶️ Procedures
1. Place a sponge, cotton balls, or other absorptive material into a heat-resistant container, such as a ceramic baking dish.

2. Pour isopropyl alcohol into the heat-resistant container, enough to soak the absorptive material.
​
3. Place a wire trashcan into the middle of a Lazy Susan.
​
4. Place the container of isopropyl alcohol into the trashcan.
​
5. Using matches or a lighter, ignite the isopropyl alcohol inside the container.
​
6. Gently spin the Lazy Susan.
​
Note: To smother the fire and extinguish the flames, place a heat-resistant lid overtop the container until the fire is put out.

This is an interesting experiment to show the total internal reflection. We get the total reflection if the light enters to an optical less dense material and the incidence angle is big enough. The incidence angle at which the ray refracts exactly along the boundary line, is called the boundary angle of the total reflection. With the total reflection we can lead the light along the curved ways, as optic fibres or water jets. This is physics experiment for science project.

Zanimiv poskus za prikaz popolnega odboja. Do popolnega odboja pride, če svetloba vstopa v optično redkejšo snov in če je vpadni kot dovolj velik. Vpadni kot, pri katerem se žarek lomi ravno vzdolž meje, se imenuje mejni kot popolnega odboja. S popolnim odbojem lahko svetlobo vodimo po zakrivljenih poteh, npr. po optičnih vlaknih ali vodnem curku.

Simple density science experiment that you can try at home to see how liquids and objects with different densities behave. Using three fluids (syrup, water and oil) we can see they clearly have different densities, and form clear layers. By dropping items with different densities into the glass, we can see which fluids are denser than them.

Title:
Physics Experiments you can do at your home #ScienceExperiment #OpticalIllusion #FunWithPhysics

Description:
In this fun and mind-blowing science experiment, we demonstrate how an object can seemingly disappear without any hand tricks! By using the concept of reflective index, we make a test tube and a beaker "vanish" in plain sight. Watch closely as light plays a trick on your eyes! Want to know how? Stick around till the end and test your science knowledge. Can you guess what reflective index is? Let's dive into this fascinating world of physics!
