Our Orbyts team worked super hard in our free time to write our first Impact report based on the last 6 years of programme evaluation, so we're mega excited to share it with you: orbyts.org/impact
We're delighted to present Orbyts' first Impact Report! Over the past six years we have seen Orbyts' transformational impact on young people, researchers and teachers alike and we’re excited to share that with you.

4 days ago our team proposed ground-breaking, unique, new planetary observations that cannot be completed by any other spacecraft in existence. That spacecraft is soon to lose funding despite being a fully functional NASA flagship. Please help save @chandraxray

#LT La solution : contrairement à Li et Na avec une transition p→s émettant de la lumière du spectre visible, le potassium a une transition 4p→4s dans le domaine infrarouge.
Et c'est très bien expliqué par @declanfleming pour @RSC_EiC :

Nice one! I work in the other direction (⚪️➡️🔵) for photo-oxidation of methylene blue with common chemicals and without tin ions. But I am too lazy to write a paper about it. 😅

Moss killer, fish medicine and fizzy drinks are what you'll need to show reversible photobleaching in this homespun version of the classic. Inspired by @pchemstud's demo. #KitchenChemistry nitter.gq/pchemstud/status/15113…
Half of this solution of thionin dye and iron (II) is exposed to light 💡 ⚛️🧪 #Chemistry #science

Recently, @AlchemistAngus and I found a sodium-vapour lamp from an old polarimeter. It reminded me of the effect that old street lights used to have on the colour of certain objects. We illuminated some acid-base Indicators, some interesting results...youtu.be/dgkAAsX1V0I?si=0Mkf…

It turns out that sparkling water and raisins are *fascinating*. My daughter and I happened upon this effect playing together in the kitchen a long time ago, and I couldn't help but explore the system more deeply... 1/n arxiv.org/abs/2308.12927

Do you like to use props to help your students visualize things? I made these cubes with the volume of 22,7 liters using 3d printing and plastic straws. That is the volume of 1 mole of any gas at STP conditions. Made with @tinkercad.
