So i missed out on 2 weeks of productive work :(
But i guess it's okay because i'm nearly done anyway..
Just need to add some finishing touches and it should be fine :)

From this experiment, it was found that the Red coloured candle burnt the fastest. At last my predictions came true! Red was the one to finish first at a time of 21 minutes and 15 seconds. This time, the white coloured candle came second last following behind the Green candle who subsequently was the slowest to burn. At first, the Yellow candle was in the lead to be the one who was going to burn the fastest. When comparing the results of Red and Yellow, at the 15th minute, Yellow measured 3.6cm while Red was 4cm then at the 18 minute mark, Yellow was 2.5cm while Red was 1.7cm! Within 3 minutes Red had decreased in height by 2.3cm! Yellow made the most wax that went in all directions (below picture). Comparing the results from the first experiment and the second, I saw a pattern that the White and Green coloured candle were always the ones being last to be burnt. So if you're looking for a long-lasting candle, buy either a white or green and try not to purchase a Red colour candle as from my observations and testing, this was the colour that burnt the fastest.














1st Experiment Video

Aim: To determine and find out which colour candle burns the fastest. 
Fast-forward mode. Watch :)

At the start, all candles were 8.5cm. 
Yellow was the fastest to burn in this experiment. 
White was the slowest to burn making it the most long-lasting 
compared to the 5 other colours IN THIS EXPERIMENT.

From this experiment, it was found that the Yellow Candle burnt the fastest. In my hypothesis, i predicted that the Red candle would have burnt the fastest, but as we have investigated, Red was the candle that actually came close to being the first one! I was very surprised at this discovery as i was adamant that Red would have burnt the fastest, but that's why we need to do another experiment to see the consistency of results. After the 12th minute, the Yellow candle was outstanding from the rest, it was clear that Yellow would be the one that would burn the fastest. However, at the 15th minute mark, Red came racing by which made it neck-to-neck with Yellow, both measuring at 5cm. Yellow then ended at a time of 22mins and 18secs, which declared that this was the colour that burnt the fastest out of the rest. The last candle standing was White measuring at the time of 35mins and 19secs. The difference between the slowest and fastest time length (35mins 19secs minus 22mins 18secs) is 13mins and 1 sec.
