|I will win the science fair and rock the world|
The following experiment includes Mentos, soda and a condom as well as a very enthusiastic instructor speaking Spanish.
The combination of these elements will most certainly be manifested in your child winning a blue ribbon at the next science fair as well as getting a detention for using a rubber in front of impressionable young people.
I'm not sure how screaming in Spanish will figure into this scenario but I'm pretty sure that they will be able to test out of it when they hit high school.
