You can do it safely with a regulated co2 dispenser. Set your injector pressure to under 60PSI. 3-liter bottles have larger mouths than smaller PET bottles. That makes it easier to get your fruit in (and out). You can get caps at www.FizzGiz.com and co2 injectors at Genuine Innovations in Tucson, AZ. Be sure to ask for the HOT sprayers.

Unless you're able to do the calculations required to determine a safe amount of dry ice, this experiment can take a really, really bad turn. The iSi whippers however are safe to use with the designated soda chargers (which contain carbon dioxide). I don't know what your budget is, but you can get whippers for less than $50. I think what you refer to with "larger bubbles" is to dissolve more carbon dioxide in the fruit juices (based on what you write about "small bubbles" which are barely noticeable). To achieve this you can cool the bootle to right above freezing as the solubility of carbon dioxide increases with decreasing temperature and leave it there pressurized for some hours. Futhermore you can increase the pressure by adding more dry ice - which of course can be dangerous if you use plastic bottles... Personally I wouldn’t dare to use plastic bottles.

I was actually planning on doing this as an activity for a club, so I have to keep the cost down. I mostly want larger bubbles so it will have more of the carbonated effect. Any smaller would be kind of a letdown, because most people would expect relatively large bubbles. How big are the bubbles with this low-pressure technique here? Currently, the bubbles are so small that they end up as just a very mild tingling rather than any popping. Well actually I was following the instructions on the site

When dry ice goes from solid to gas it's volume increases dramatically leading to large pressures - and possibly an explosion...

How big can I get the bubbles to be, and do you have any times on getting them bigger? I tried carbonating fruit by filling a 2 liter coke bottle with fruit and dry ice.

I guess I was surprised that you could saturate a strawberry with CO2 by just placing it in a CO2 atmosphere. Thanks.

So if the container is filled with dry ice it will slowly displace the air as it sublimes, leavning the atmosphere saturated with CO2. The amount of CO2 that will dissolve in the strawberries will be dependent on the temperature, pressure and concentration of CO2. The experiment is performed at ambient pressure, a temperature close to 0 °C and in pure CO2 gas. The only way to get more CO2 to dissolve is to increase the pressure. The safest way to do this is to use a iSi container which is designed for high pressures (<a href="http://blog.khymos.org/2007/04/09/carbonated-fruit-the-isi-way/" rel="nofollow">blogpost</a>). Do NOT pressurize a container using dry ice! Jurgen,

If you do not freeze you cannot oversaturate the strawberries with CO2 under ambient pressure? Or am I mistaken. Will try it nevertheless, enough dry ice (and liquid N2...) in our lab.
