This is part of the summer reading program at the public library closest to our house - really! Science stuff every Monday afternoon. I'll bet many of you recognize this. It's the old "Mentos in a two-liter bottle of soda" trick. The Diet A&W Root Beer exploded tallest, that's what this photo shows. It was very funny that the girl on the right was trying to measure the height of the explosion with that puny yardstick. This was the result of adding 10 Mentos. The kids all wanted to add 100 after they saw the results. The librarian asked the kids if they knew where Mentos were made. My daughter raised her hand and said, "China." Probably because we joke a lot that "everything" is made in China.

Makes for a great picture, I love the soda stopped in mid air. I have never tried this, but I think I am going to do it now.
ReplyDeleteHi Jim - you get taller explosions if you use a tube at the top of the bottle. www.geysertube.com - or you can buy them at stores like Target. It helps get the Mentos into the bottle quick, because the reaction is very fast! And, you can still drink the soda afterwards, and yes, it still has fizz.
