My friend and i are doing a science fair experiment with bottle rockets but we lost the paper with all of the important stuff. please help. =)

Answer: you could.. make a bottle rocket?
geta bottle, stick some paper fins to it
fill 1/3 with water and pressureise using a pump, making sure the bottles upside down, and eventualy after pumping then bottle with go wooooooooosh

another one you can do, get an empty drinks can, and heat it with a bunson burner, for about 2minutes.. then using heat resistant gloves put the can into a volume of water..
and this will make the can ‘implode’ and crumple
hope that helps x

Question: Magic Tricks?

Rather than giving a question, I request for some tricks you can do with mathematics. I have a party for my science class and the topic is most likely magic tricks. If you can’t think of math, think science. The most surprising trick will definitely get best answer.

Answer: how about this
Let a and b be equal non-zero quantities
a = b
Multiply through by a
a^2 = ab
Subtract b2
a^2 − b^2 = ab − b^2
Factor both sides
(a − b)(a + b) = b(a − b)
Divide out (a − b)
a + b = b
Observing that a = b
b + b = b
Combine like terms on the left
2b = b
Divide by the non-zero b
2 = 1

Question: I need help with my science fair experiment!?

My science fair experiment is to see who has better short term memory, male or females. I’m going to test them by comparing a pair of males and females of the same age. Could you please do this on any member of your family…. first write down these numbers:
1

23

98
then give the person 1 minute to look at the 6 numbers. after one minute let them recite them back to you. Please write your first name and correct age and how many numbers you remembered to answer. THANK YOU TO ANYONE WHO DOES THIS!
