BIG QUESTION Which fruit has the strongest fiber-strength?
If I were to put a fire-cracker in a fruit, how well would it hold out?
Which fruit would hold out best?Why?

HYPOTHESIS I think the apple has the strongest fiber
strength of all the fruits because when you bite into it, it’s harder to get through it then it is a lemon. The kiwi I think has the lowest fiber strength.

INTERESTING FACTS Bananas were introduced to the American public in
1876 at the Philadelphia Centennial Exhibition. Bananas are one of the best sources of potassium. Eating an apple is a more reliable method of staying
awake than consuming a cup of coffee. Watermelon is 92% water, cabbage is 90%. Pumpkins are not a vegetable, they are a fruit. So are
avocados. Tomatoes were once considered a type of apple by
France and Italy. Tomatoes used to be yellow, not orange or red. A stalk of celery only contains 10 calories, so eating it
makes you lose weight.

EXPERIMENTMaterials
A) Various fruits: Lemons, Apples, Grapefruits, Kiwis, etc…
B) Small fireworksC) PaperD) A tube or Jar with a hole in
the sideE) A lighter or box of matchesF) A knife to slit a hole through
the fruit.
InstructionsA) Cut a hole in the fruit big
enough for the fireworks to fit in
B) Slip in the fruit and firework into the fruit, then place a piece of paper inside the jar
C) Put the fruit and firework in the jar Make sure the wick can still be light.
D) Light the fruit. Pull lighter back quickly. For better results, video tape in slow mode.
E) After the fruit has exploded (if it did) remove the fruit and throw it out. Examine the paper
F) While waiting for the paper to dry, perform experiment again with another fruit
Control VariablesIn order to control my experiment, and collect data accurately, I video taped each fruit, and weighed and measured each fruit.

OBSERVATIONS FROM EXPERIMENTS If the fruit had a shell, like the grapefruit and
orange, they split where the firework was placed, or didn’t explode at all, but if you opened it, you could see it had obsorbed the firework.
Fragile fruits, such as the kiwi and lemon, were quicker to explode.
Hard fruits, such as pears and apples, split and separated in pieces.

ANALYSIS The experiment tested my hypothesis I know this because the papers showed how
much the fruit exploded
![Page 9: S CIENCE F AIR P OWER P OINT By Kyra Ferguson. B IG Q UESTION Which fruit has the strongest fiber-strength? If I were to put a fire-cracker in a fruit,](https://reader034.vdocument.in/reader034/viewer/2022051301/5a4d1af37f8b9ab05997f6d8/html5/thumbnails/9.jpg)
CONCLUSION My hypothesis was wrong, but the apple came
close to being the strongest. I wouldn’t have changed anything in my
experiment. Questions I have for next timeHow well would an egg survive if I preformed this
experiment on it? Does having a peel around a fruit affect its strength? Would using a different set of fireworks affect the
outcome?
