2. What was the Bomb?
Pressure Cooker Bomb
It’s a Bomb that deals with a pressure
cooker.

3. How Do they Work
You use the pressure cooker to create
pressure in the pan and when there is
too much pressure they explode. You
put things like nails and metal in there
so when it explodes, it flies out.

4. Why They Were Effective
They were placed in a spot where there
was a lot of people, and also for the
runners when they got there and the
bomb blew and they just been running
for 4 hours. So they were sad that they
ran all of that so they would lose
something. Lastly it was so bloody
everyone was scared.
