16. The Vacuum Cannon!

Post by Thomas W-P » Thu Feb 14, 2019 9:30 pm

(Original post plus listen to podcast)

Thomas, Robin and Patrick Kaplo discuss the amazing vacuum cannon and how it can be used to make physics thrilling. The cannon is now available in the shop. Buy it and you’ll be supporting the podcast while you have a BLAST!
It is half term next week in the UK so it will be two weeks until episode 17.

SUMMARY
Patrick Kaplo joins the team to talk about the brilliant Vacuum Cannon. This is a recognised piece of equipment, although Thomas and Robin had not heard of it. Thomas built one and tested it with spectacular results. All schools should have one! The cannon is actually covered in detail by CLEAPSS and they give full instructions (with links to where to buy parts) on how to make one (CLEAPSS login needed).

Thomas was so keen to spread the joy, he decided to sell the cannon in our shop and you can pick one up for £20 (including P&P but you need to enter the code BOOM at checkout). You can also support the podcast by purchasing a small upgrade that includes a £5 donation.

WAYS TO TEACH… DISTANCE, SPEED AND ACCELERATION
Episode 20 (assuming we make it) will be all about ways to teach distance, speed and acceleration (or displacement, velocity and acceleration). How do you do it and what works best for you?

You can also message us via our website contact form at the.physicsteachingpodcast.com, Twitter @physicstp, email using the address given in the podcast (if we remember) or by leaving a voice memo using WhatsApp or Telegram to the phone number in our Twitter profile, +44 7898 814716 (don’t call the number, nobody will answer, just hold down the microphone icon and speak your message). Don’t forget to tell us your name because we may use your audio in a future episode. Please do leave a voice memo: Thomas thinks nobody loves him.

The music we use remains One legged equilibrist polka by Circus Homunculus.

Patrick’s theme tune is from Hail to the Chief Bluegrass Banjo by Tom Adams from BanjoNews.com under Fair Use.
