### Purpose

• To measure the reactions of pressure on oobleck when the water and cornstarch ratios differ in formula.

• To determine if the oobleck will splatter or stay together as it become solid when it hits the ground.

### Method

• With the oobleck we will fill 12 inch balloons and drop them from our gondola using a motor from a remote controlled boat and a remote.

• Balloons are filled with oobleck. Other balloons are filled with pancake.

• When the balloons pop we will measure the radius of the spatters

### Hypothesis

• We hypothesize that if we increase the amount of cornstarch and decrease the amount of water the oobleck will harden more and therefore splatter less.

• On the contrary, we believe the pancake batter will have the greatest splatter.

### Design

• We used a double door gondola with pins to hold them closed.

• The motor and remote pull the pins and release the balloons.

• Two balloons can be dropped at the same time.

### Engineering Process

• Took a motor from a remote controlled boat

• Attached two nails to the motor with string so when it spins it pulls the pins and releases the balloons

• We will send signals from the remote to the motor using a transmitter and receiver.

### Data

The balloon filled with pancake batter popped from 110 ft with a radius of 8’6” ( 9about 2.6m), however the oobleck balloons did not pop and simply hit the ground and stuck together with out popping the balloons

### Conclusion/Analysis

• Our hypothesis was partially correct because the oobleck stayed together as it hit the ground.

• But the error of the balloon not popping makes it impossible for us to know if pieces of the oobleck would have exploded out past the pancake batter.

• Therefore the answer for our hypothesis of the pancake batter splattering farther is unclear because the oobleck filled balloons did not pop.
