Ejaculating and vapourisation

Mentos plus coke? What good could come from a tube of candy and a bottle of soda? Well, a magnificient display of an ejaculation of coke shooting up as high as 2m. Projected. What happened today when we tried out this experiment which was to be used as our science project for the upcoming science fair was only a gush upwards of 1m at most lasting around 2 secs. The prospect of us making the coke to shoot upwards higher is good. We didnt perform the experiment properly. 1st of all, we couldnt drop many mentos's into the bottle as we have not get a tool to hold 8-10 mentos and drop it all at once. We only managed to drop in 5-6. 2ndly, the carbon dioxide inside the bottle( That's what gives the soda the fizz) was released partially when i turned the bottle cap. This is the result of the bottle rolling around in the car when i drove to sch in the morning. My bad! 3rdly, i think that it would be perfect if we could get a 2 litre bottle but alas, the only manufacture 1.5 litres here in malaysia. If we could get these 3 factors accomplished, we should have a fantastic ejaculation!
We were also trying out our 2nd experiment in which we create a cloud in a bottle. Key ingredients? Smoke, a little water, a pump and an empty bottle. We started burning the matchstick then putting it out before placing it inside the bottle to be accumulated. Then we poured in some water. Around 15ml and sealing the cap and starting pumping air into it. So we started pumping and after 15-20 pumps, the bottle hardens. We pulled out the pin(connected to the pump) out from the bottlecap and all we heard was a soft PsssssssTt with no smoke. Not a loud pop and the bottle with white smoke as i've seen from the internet.
We made substantial progress on our 2nd attempt with a little white smoke filling the inside of the bottle. But on our 3rd attempt, we managed to get the bottle filled with white smoke. We tweaked the amount of ingredients, with more smoke accumulated inside the bottle and lesser amount of water putting only 5ml or equivalent to a filled bottlecap.
We'll be exhibiting our project on the 23rd of june at our sch's science fair and i hope everything goes as planned and we'll put up a good show for all to admire. Oh, i'll be trying to get my teammates to agree to the name Ejaculation & Vapourisation. ;) Cheers!!
