Robin asks Thomas what the bits and bobs were he sent home to his A-Level students. What would you send? Tell us by tweeting @physictp #tptpbitsandbobs

Thanks to Frank Noschese for pointing us at the “String and Sticky Tape Physics” PDFs: http://www.arvindguptatoys.com/arvindgupta/edge-one.pdf and http://www.arvindguptatoys.com/arvindgupta/edge-two.pdf .

We also mentioned Laura Pankratz’s speed of sound measurements with a bottle. There are similar experiments here https://www.thenakedscientists.com/get-naked/experiments/blowing-bottles and here https://www.physicslessons.com/xlab-speedsound.html If anyone can find a good set of instructions for how to do the measurements with home kit (and video it pleeease ) then we would love to promote it!

Also, we couldn’t find the experiment Thomas refers to where you tie weights together so that they pull the next one off a drop and end up with string spacing such that the sounds of the weights hitting the floor are regular. If you can come up with a good story as to how this might work at home, let us know!

Please share ideas or successes – or indeed questions by messaging us on BlueSky: https://bsky.app/profile/physicstp.bsky.social .  You can also message us via our website contact form on every page of the web site at  the.physicsteachingpodcast.com, or email using the address given in the podcast (if we remember). We are moving away from X but can be found there as @physicstp.
