Melde's experiment using El wire works really well. Thanks to my colleague Rina for the suggestion & setting it up 👍 CLEAPSS 🏁 Samir Moezzi #waves #physicsdemos #electroluminescence

Today we're proud to be in the UK Parliament demonstrating repair and talking about #RightToRepair with MPs, allies, community repair groups from all over the country

Forgot I kept these dogfish lenses when students did fish dissection 🐟 They do fluoresce nicely under UV light #FluorescenceFriday

For your delight, the most beautiful materials library in the world is now online with new interface. Do visit its FREE to all thanks to UCL Institute of Making instituteofmaking.org.uk

Labour of materials love by whole UCL Institute of Making Team but especially our Materials Librarian Sarah Wilkes and Director Zoe Laughlin

4/5 people want the government to support repair more. But our politicians don’t seem to have noticed...yet!⁠
⁠
We’re bringing repair to them by running a repair event at parliament!
⁠
We need you to invite your MP using our simple tool at: tinyurl.com/MP-invite ⁠📢✊🔧

I didn't realise benzil was so excitable until my violet laser pen (absolutely deliberately 😇) hit these crystals grown by Iain Smellie. Happy #FluorescenceFriday everyone! 💚

The four photochromic LEGO amigos are ready! First, we irradiate with UV illumination & they emit red fluorescence. Once source removed, turn red & with bright white light they return to original yellow colour. #spiropyran #photoswitches #FluorescenceFriday Royal Society of Chemistry

Happy #FluorescenceFriday Mentos with bits that fluoresce under UV light #riboflavin #glowingsweets

2,4-DNPH again?

Photon momentum from a violet laser pen pushing the vanes of the Crookes Radiometer 😉... but wait the propellant from a compressed air can reverses the direction of rotation? Can you explain it? #studentchallenge #Physicsfun #heatengine

Another droplet reaction, this time a pH indicator colour change due to sulfur dioxide youtu.be/6PSTMmtZugM?si…

A new version of a #Gardenindicators bleaching experiment I did a few years ago here youtu.be/hPlyq2WbS0M?si… I used poinsettia last time, raspberries and brambles this time.
