Science and Sunflowers

Sunflowerfest is an annual three-day festival of music and art held just outside Lisburn, Northern Ireland, priding itself on its family friendly atmosphere and sprawling spectrum of creative activities. Unlike the monster festivals that are held in other parts of the UK, in Northern Ireland our festivals are small (think a few thousand people, not a few hundred-thousand) with a strong focus on local talent. The perfect place for some experimental, creative science outreach…

In 2016, I contacted the organisers and floated the idea of a science outreach stall based upon my research and others in BRIDGE and the Cabot Institute. The idea, called Living Earth, was new, reasonably grand and completely untested. The response was a very enthusiastic “yes please!”

So, last year a squad of five outreachers (Alan Kennedy, Emily White and Michael Cooper of the Cabot Institute, plus Dewi Owen and Zuleika Gregory our puppeteers) arrived in blustery Northern Ireland and over the course of the festival recreated the entire history of Earth. 4.5 billion years in 3 days. With the help of punters at the festival, we built a 1.5 m diameter model of the Earth out of willow, foliage, recycled and craft materials. As the Earth was built, we recreated many of the major processes and events that shape it today, from the placement of the continents, the expansion of biomes and climate zones, the formation of the cryosphere and the destruction of the Anthropocene.


As well as this geological ‘Big Art Attack’, crafts and a puppet show entitled This Soup Tastes Funny! about the evolution of life were put on in the festival’s dedicated Kids Zone. Our puppets, Doug and Barry, had to travel back in time to the primordial soup and race through evolution in order to relive the first day of the festival. Five time periods, four puppet costume changes, asteroid impacts, crowd participation and even a song left the young audience both entertained, but also possibly very confused… That’s a lot of science to take on-board in 15 minutes!

We (and our marquee) got battered by wind, rain and the exhausting amount of activities we were juggling, including our recreational ‘time off’. However, we certainly offered something unique at the festival and left a positive impression with the organisers:

“Just to say THANK YOU to you and the crew for all the great things you did at Sunflowerfest. So appreciate everything you do and did. We would always welcome you back to do whatever you would like!” – Vanessa, Sunflowerfest Organiser

Now, I have quite an active imagination, so that last sentence was a dangerously open invitation… With 2017’s festival theme being ‘a parallel universe’, I thought something immersive on the theme of deep time would fit right in. The new plan was to build a time machine! Or in other words transform the inside of a marquee into a jungle, to show what Ireland would have been like during the hot Eocene period ~50 million years ago. As I wrote down a proposal for the festival application, this seemed like it would be reasonably straightforward compared to 2016. In hindsight, I misjudged that.

Logistically, constructing a jungle was only possible because my mum had recently had some trees in the garden felled and she also had several hedges needing cut back. A supply of logs and some waxy leafed laurel and bay that would hold their colour after cutting for the duration of the festival made a good, but somewhat bulky start. These were attached to the marquee ceiling and a heavy metal tripod to give us a central ‘tree’ and performance space to demonstrate some tectonic themed experiments. Ferns and other leafy plants were then dug up and temporarily housed in buckets to fill out the back of the tent and childhood toys added around the stall for the jungle fauna. Finally, a small speaker playing jungle sound effects was hidden up in the canopy to complete the experience.


Obviously, a hearty dose of imagination was required to convince yourself our locally sourced, temperate vegetation was an Eocene jungle, but luckily this year our stand was based entirely in the Kids Zone, where imagination is not in short supply. Ideally, I wanted to have a Superser heater in the back of the tent to raise the temperature to 35 °C, but doubted that would pass the risk assessment. We settled for having the ambient Northern Irish temperature, but luckily, we did have a few biblically heavy rain showers to give it a nice wet rainforest feel. It took three days of preparation, cutting, digging and replanting vegetation, and five hours of construction, but eventually we had the most eye-catching stand in the whole Kids Zone. It was pretty much the Eocene.

In our jungle, we had information about how Ireland has changed over the past billion years, a floating plate tectonics game and crafted fossils and jungle wildlife to decorate the stand, all of which kept us mostly run off our feet during our three-hour slots each day. Our flagship performance however, was a bicarbonate soda-vinegar erupting volcano, as ~50 million years ago Northern Ireland was at the centre of lots of volcanic activity, forming for example the Giant’s Causeway. Without a single trial run (we spent all of our preparation time building the jungle), our resident chemistry undergraduate, Oliver Feighan, carried out the experiment in front of an audience 40 strong. It was possibly the least explosive or inspiring volcano in the world. As the foam dribbled out the top of the bottle it was met with a slow and bemused round of applause. Those kids will definitely go on to be the environmental scientists of the future.

Creative outreach at big events may not always go quite to plan, it takes time and effort and you can sometimes bite off more than you can chew, but it’s a great way reframe the relevance of research in a totally different way, speak to a new audience (a very bohemian crowd, in the case of Sunflowerfest) and just do something fun. It’s not often families can experience palaeoclimate, tribal drumming circles and the Rubberbandits* all in one day. We ended up going on to run the globe building activity from 2016 at a further two events (you can see a highlight video of the almost finished piece here). Although kids and parents found 2017’s time machine a lot of fun and it looked surprisingly effective, unfortunately I don’t think I will have time or energy to ever recreate the Eocene again! However, while I may be leaving the Eocene in the past, I highly doubt this will be my last Sunflowerfest.

Converting probabilities between time-intervals

This is the first in an irregular sequence of snippets about some of the slightly more technical aspects of uncertainty and risk assessment.  If you have a slightly more technical question, then please email me and I will try to answer it with a snippet. Suppose that an event has a probability of 0.015 (or 1.5%) of happening at least once in the next five years. Then the probability of the event happening at least once in the next year is 0.015 / 5 = 0.003 (or 0.3%), and the probability of it happening at least once in the next 20 years is 0.015 * 4 = 0.06 (or 6%). Here is the rule for scaling probabilities to different time intervals: if both probabilities (the original one and the new one) are no larger than 0.1 (or 10%), then simply multiply the original probability by the ratio of the new time-interval to the original time-interval, to find the new probability. This rule is an approximation which breaks down if either of the probabilities is greater than 0.1. For example

1-in-200 year events

You often read or hear references to the ‘1-in-200 year event’, or ‘200-year event’, or ‘event with a return period of 200 years’. Other popular horizons are 1-in-30 years and 1-in-10,000 years. This term applies to hazards which can occur over a range of magnitudes, like volcanic eruptions, earthquakes, tsunamis, space weather, and various hydro-meteorological hazards like floods, storms, hot or cold spells, and droughts. ‘1-in-200 years’ refers to a particular magnitude. In floods this might be represented as a contour on a map, showing an area that is inundated. If this contour is labelled as ‘1-in-200 years’ this means that the current rate of floods at least as large as this is 1/200 /yr, or 0.005 /yr. So if your house is inside the contour, there is currently a 0.005 (0.5%) chance of being flooded in the next year, and a 0.025 (2.5%) chance of being flooded in the next five years. The general definition is this: ‘1-in-200 year magnitude is x’ = ‘the current rate for eve

Coconuts and climate change

Before pursuing an MSc in Climate Change Science and Policy at the University of Bristol, I completed my undergraduate studies in Environmental Science at the University of Colombo, Sri Lanka. During my final year I carried out a research project that explored the impact of extreme weather events on coconut productivity across the three climatic zones of Sri Lanka. A few months ago, I managed to get a paper published and I thought it would be a good idea to share my findings on this platform. Climate change and crop productivity  There has been a growing concern about the impact of extreme weather events on crop production across the globe, Sri Lanka being no exception. Coconut is becoming a rare commodity in the country, due to several reasons including the changing climate. The price hike in coconuts over the last few years is a good indication of how climate change is affecting coconut productivity across the country. Most coconut trees are no longer bearing fruits and thos
