If you put those winter green life savers in soda you get a similar reaction to the mentos as well.. I am thinking we may try a few diffferent kinds of mints for our volcano when we are done.. I still need my bottom card board for that one... then we will use plastic and make a cone inside so it is reusable, infact we may be using an actual board underneath to mount it on for the same reason.... this volcano keeps growing!
"Backyard Ballistics" is a GREAT book, but I'm not sure it has anything to do with actual explosions. There's another called "The Fine Art of the Catapult" or something of the sort. Phillip saw them in a catalog at age 5, and made me check the library. Yes, it carried BOTH! If we move out to the country, we're going to buy them, and his education will take a decidedly more projectile track!
It doesn't work well unless you put the candy into a just opened bottle of soda. . .as my son says "with fresh fizz". ;-) So if you're doing a volcano. . .you have to build the volcano to hold a liter of soda. BC of the shape of the bottle, we've had better luck doing the old baking soda and vinegar trick. Make a well with lots of baking soda. . .and then pour in vinegar that's been premixed with a drop or two of dishwashing liquid to make it flow more realistically. ;-)
oooo I like the bubbles idea, I wonder.. does anyone know how to make the fake snow bubbles? you knwo the kind the use for christmas stuff?
YEah I have lots of books to look at here too about science stuff but ds has his mind set on the one thing, his teacher is going to help although when he did it at school he left a huge mess and that is because the teacher did NOT supervise him but went to the student lounge and gave ds permission to go do it on his own. he expected him to do it in smaller doses than he did! Guess the chemistry teacher needs to give a bit more instruction in safety, and amounts for experiments! So ds had to clean the whole room for doing it wrong, and all. I let ds know I was not impressed with him doing it with out a teacher there and told him that he may do it at home outside WITH dh with hiM! I also told him he would wear a lab coat and all the safety gear including gloves! I don't want him thinking he can just toss chemicals around and see what happens, if he is going to play mad scientist he has to be cautious.
