Chemical Engineering Challenge 2009

11 March 2009, the three future chemical engineers, Candy, Wen Zhe and I took part in the Chemical Engineering Challenge 2009. The challenge is to use the power of mentos and coke to lift a weight. The team with the greatest height will win. How?

Design yourself.

So, we wasted more than 20 rolls of mentos and 10 bottles of diet coke for our experiments. The erupting power of the coke and mentos was far beyond our expectations. One mentos (only) and 2 litres of coke... the eruption was so instantaneous. Anyway, it was fun. We had ourselves soaked in coke, and even doing experiments outside at 2am. Haha.

We scrapped so many ideas.. Calculation part was frustrating. Thanks to my dear the future mechanical engineer's help.

first attempt, failed

attempt before competition at 2am, failed

Competition

the PHD team

he buried his thing in the ground.. why??

he used the expansion of gas to push the weight

he's chopping the bottle

heating up the coke

our turn

we used 20 mentos and this is what was left

the team that got runner-up

trying at the bridge for greater height, 2nd round

We were the Champion!! Although we didn't get the greatest height, we won by creativity! haha.
The greatest height was 6m and we got 5m. Well, for the first round, only our group succeeded.

It was fun.... Full of fun. I didn't regret taking part. WOOO!
