Huge thanks to everyone who made the Festival such a brilliant night. Here’s to the sparks — big and small — that keep us going. Whether you’re outdoors amongst nature or finding a quiet moment at home, I hope you discover something today worth celebrating. Here's one of mine! ✨

If you’re having a rough day, please know this: progress isn’t about “carrying on as normal”. It’s about noticing and celebrating the little wins — a moment of laughter, finishing a task, enjoying a view. Small sparks of joy matter and can change the feel of a whole day.

What you don’t always see behind the microphone is that I live with a progressive heart condition. It’s unpredictable, exhausting and mentally challenging. Yet standing there on Saturday, part of the atmosphere and joy, reminded me how powerful it is to keep finding things that lift you up.

🔥 What a weekend at the Festival of Fireworks, Catton Hall! Thousands gathered under the night sky for a spectacle of colour, sound and shared awe — and I had the privilege of being host. 🎤 Nights like these remind me why live events matter.

They are set up on trestle tables, with laptop screens visible and the lids of the hard-plastic cases of the control panels open. Some of the crews can be seen in the background chatting in small groups.

Earlier this week, I was fortunate to be part of a #Cardiomyopathy UK visit to #CureHeart Labs @ox.ac.uk . We went behind the scenes to see cutting-edge work on inherited heart conditions. Lots of uplifting conversations between researchers and patients giving real hope for progress.👇

This morning's partial #SolarEclipse, evidenced by my solar panels. 😎 Cool, eh?

For the first time ever, I'm actually able to attend an @equitybwm.bsky.social meeting. We've had some amazing speakers today and now we are onto serious union business. Very glad to be part of this. Together we are Stronger.

Bring extra sparkle to your festival with a science and maths infused fire and art mashup.
Drop me a line if you are interested. I adapt the size and scale of the shows for each venue.

Matthew is on stage in a large Victorian City Hall venue, with a high arched ceiling and theatrical lighting overhead. In the foreground is the audience who are watching the show. A six-metre high wall of pyrotechnic gold and silver sparks is erupting at the front of the stage with dramatic effect.

A stonking finish to British Science Week at the weekend, with headline shows at #ColliderFest.

I left a little decorative post-show souvenir at City Hall. 😄 #Hull #BSW25

Lovely to join the friendly @benendenbells.bsky.social ringers this evening, although it did require a lot of knots in my rope. Me and my high heels... 😆 #bellringing

Mid #BSW25 school shows. I was very tempted to shave my head, paint myself blue and hit the table with fluorescent sticks.
A very blue, darkly-lit stage containing a table and some black wooden boxes. The photo is so blue that it is almost not worth posting.

Tosh downtime this afternoon is taking me back to my degree year abroad, when I first discovered Moroccan cuisine.

I suddenly have an urge to fire something in celebration, however my shows aren't until next week.

MUST RESIST.

18 months on, and this still feels surreal, even for a clued-up #scicomm pro!

A clinic in another part of the country can access the implant INSIDE my body to check that I am safe. 🤯

Flippin' marvellous! 🫀😀

This time of year = Site visits and consultancy. Bit soggy under foot, but lovely sunny spells are a bonus. 🙂

When I am big and grown up, I want to go to conferences and communicate through the medium of purple modelling clay, rainbow lollipop sticks and sparkly pipe cleaners. 🙏😀✨🌈🦄 #SciComm

Back from a much-needed holiday. This is my favourite photo from the week.

Any guesses as to where this was taken? 🤔
No peeking here for clues! You are looking at the underside of a civil engineering structure. It features triangulated girders and a cantilever deck running along the left and right sides. The blue sky has a few white clouds visible.

Happy place: 🔔 @bristolcathedral.bsky.social ringing chamber 🔔

I've spent many hours up here over the years and did some stints as Ringing Master many moons ago. Today, I'm here with the Welsh Colleges Society of Change Ringers. #bellringing
The (nearly) white-walled ringing chamber of Bristol Cathedral. Twelve blue rectangular peal performance boards are displayed on the facing wall, with an additional two on the left wall, each featuring a different performance scribed in gold lettering. In the foreground are seven visible ringers out of eight who are ringing on ropes with blue wool sallies.

We've moved on to inventing our own #SciComm movie characters. Ours is a skiing hairdresser. The big ears make them a good listener, vital for being an effective engager. #UKSFN
A plasticine character with big googlie eyes. It is on green skis, made from ice lolly sticks, and is holding tinsel scissors.

I'm at a conference. The current presentation features a photo of the Coventry ring road*. This is way too much excitement for a Friday afternoon.

(*Radford Road junction, I think?)

It is #LGBTplusHM25, but did you know that it is also #HeartMonth? Do you know CPR? It's never too late to learn or refresh your CPR training? Lots of info and advice at @resuscounciluk.bsky.social.
