AIM Our Aim is to see which fizzy drink will react the most when we put the Mentos in. Which one will shoot the highest for the best reaction.

Control We will keep the amount of fizzy drink the same in each bottle. (1.5 litres.) We will have the same flavour and amount of the Mentos.

Hypothesis Jaymee: “I think the Lift drink will have the best reaction and shoot the highest.” Sophie: “I think Fanta will explode the highest.”

Variables The drink flavours will change.

Conclusion Our hypothesis’ were both incorrect. It was actually the coke that exploded the highest. We think that the Fanta was the worst because we left the lid off the bottle for too long before we put the Mentos in. We think that carbon dioxide escaped before we put the Mentos in. Some of the bottles had less Mentos because they got stuck in the funnel. It all happened so quickly. That made it unfair for the Sprite. The Sprite may not have reacted as well because it only got seven Mentos in when it was meant to have ten. They fell out of the funnel as we tried to put them in. If we did the experiment again we would measure the explosion from the lip of the bottle, not from the ground. We think this would have been more accurate. We would also make a better funnel.

Results The coke had the best reaction and it went the highest. The coke went 75 cm high. Then the sprite went the second highest and it went 50 cm high. Lift and Fanta just bubbled over and did not really explode, it just looked like it had puked over the rim of the bottle. We had to work really quickly because it reacted so fast
