Students Open-mouthed at Chemistry Spectacular

Students from four schools in and around Brussels were left open-mouthed as Prof István Markó and his assistant Fabio Lucaccioni performed their chemistry demonstration lecture “Chemistry and Energy – a Tasty Marriage” at the Université Catholique de Louvain (UCL) site in Woluwe, Brussels on Tuesday March 20th. Two lectures were organised on the day by the RSC Belgium Section in cooperation with Scienceinfuse based at the UCL main campus at Louvain-la-Neuve.

The students, from St. Johns International School, Waterloo, the Verseau International School at Bierges, the Institut Maris Stella at Laeken and the European School Brussels II at Woluwe watched enthralled as Prof. Markó worked through over an hour of about 20 reactions involving flames, colour changes and explosions.


Following Prof. Markó’s advice the students kept their mouths open to equalise the pressure in their ears during the more substantial bangs. A volcano spluttered, photo flash bulbs were simulated, the heat from a ball of flame caused by burning hydrogen in a balloon was felt by the students in the front rows (see above), and a black serpent rose out of a beaker containing only sugar and battery acid. The students oohed and aah’d as blue luminescence spread downwards in a glass tube demonstrating energy generated in a cold reaction.

Enthusiastic response
Prof. Markó engaged his audience with commentary on the chemistry behind the reactions, and his steady repartee – untrammelled by current notions of political correctness – aimed to challenge their ideas and make them think ‘outside the box’. By the end of the lecture though, he had smoke coming out of his nostrils - from eating a Belgian waffle dipped in liquid nitrogen!

After the event, one teacher commented: “Our students were full of enthusiasm and excitement when they got back to school and enjoyed every aspect of the lecture”.

The demo lecture was repeated to a French-speaking schools audience at UCL at Louvain-la-Neuve on Thursday March 22nd in the afternoon and to a public audience on that evening. On both occasions the 500 capacity auditorium was packed. The total audience for all four shows was in excess of 1200.

TOTB cup presented
At the start of the afternoon lecture at Woluwe the winning team in this year’s RSC Belgium local ‘national’ eliminator of the RSC Top of the Bench (TOTB) Competition was presented with the Keith Price Cup. The winning team from European School Brussels II at Woluwe are pictured below with their teacher Julie Deegan and RSC Belgium Section Chairman Prof. Bob Crichton.


The Woluwe team will represent RSC Belgium at the RSC UK final of TOTB at Imperial College London that takes place on Saturday 31 March. We wish the team good luck for the competition and will report on how they get on in London.

The RSC Belgium TOTB Cup has renamed as the Keith Price Cup last year in honour of our first Chairman and principal "founding father" of the section.

A complete list of the experiments performed during our 2012 demonstration lectures is available on request from RSC Belgium’s Schools Coordinator Rita Woodward.

Working for a World Free of Chemical Weapons

RSC Belgium was honoured to welcome the Director-General of the Organisation for the Prohibition of Chemical Weapons (OPCW) Ambassador Ahmet Üzümcü on the evening of 15 March. The Ambassador addressed a large audience of members and friends of the section at the Royal African Museum in Tervuren.

His Excellency Ahmet Üzümcü (pictured left, above with RSC Belgium chairman Prof. Bob Crichton) was appointed Director-General of OPCW in December 2009. Immediately prior to this appointment he served as the Permanent Representative of the Republic of Turkey to the United Nations Office at Geneva.

Ambassador Üzümcü is a career diplomat with vast experience in multilateral diplomacy. He has represented Turkey at the North Atlantic Treaty Organization (NATO) Council, the Conference on Disarmament, the United Nations and other international organisations in Geneva. He has considerable experience in disarmament-related diplomacy, political-military affairs, disarmament and proliferation issues. He held the post of Ambassador of Turkey to Israel from 1999 to 2002.

Chemistry for peace
Ambassador Üzümcü described the rationale for and operation of OPCW and the Convention on Chemical Weapons. Tremendous progress has been made in the destruction of the vast majority of chemical weapon stockpiles around the world. However vigilence is still required to finally eliminate this threat and ensure such weapons do not reappear in the hands of terrorists or new nation states.

"A total ban on chemical weapons is no small achievement for the international community," concluded Ambassador Üzümcü. "We will continue to endeavour to strengthen this norm in order to keep our future generations safe from this scourge which has in the past brought death and untold suffering to those that became victims."

"My message to you is to join this endeavour; to spread the word. To use your considerable expertise, influence and good will to ensure that the norms and values that we share are more widely known and supported. To guarantee through your work with students and apprentices that the chemist will always work for the betterment of the community and never use his knowledge and skills to bring harm to fellow human beings."

OPCW is working with the International Union of Pure and Applied Chemistry to promote the services of chemistry to society, international peace and security.

The full text of the Ambassador's speech can be found here.

Following the Ambassador's talk an extended question and answer ranged over the nature of chemical weapons, current threats to peace and environmental legacy issues.

Chemistry Challenge 2012 launched

Following a small pilot run in 2010 and an extremely successful full run in 2011, the RSC Belgium Section is happy to announce the launch of its Schools Chemistry Challenge 2012.

The Chemistry Challenge competition is open to students from any school in Belgium, and we would like to make this year the biggest and best Chemistry Challenge yet!

Details of the 2012 competition format are given below. The questions will be set in English, but may be answered in English, French, Dutch or German.

The competition is open to school students in their penultimate year of High School (usually aged 16 – 17), and consists of a 2 hour written test held in school and designed to demonstrate the participants’ knowledge of chemistry and their ability to think logically. Attractive cash prizes are offered, as well as certificates acknowledging participation.

From previous experience we have found that students feel that participation is a valuable ‘plus point’ when completing University application forms, clearly demonstrating an ‘extra curricula’ interest in a science subject.

A real tester
This paper-based test of knowledge and initiative was devised by RSC member Rita Woodward and is split into three sections:

• A/ a chemistry multiple choice paper
• B/ structured questions on chemistry, and
• C/ a 'Thinking Matters' paper that is not chemistry based

In 2011, almost 80 students participated and RSC Belgium awarded cash prizes to top performers in each section with the winners drawn from the British School of Brussels (BSB), International School of Brussels (ISB), St. Johns International School and the European Schools at Ixelles and Uccle. Some of the winners are pictured recieving their awards and certificates from section chair Prof. Bob Crichton above.

Keith Price Prize
The best overall entry in the two chemistry sections was from Krithika Swaminathan (pictured left) a student at St. Johns school. Krithika was the first recipient of the Keith Price Prize established in memory of one of RSC Belgium's founding members who died earlier this year.

For more information on the 2012 RSC Belgium Chemistry Challenge, please contact our Challenge coordinator Rita Woodward. Further details of the Challenge Rules are outlined below.
