DESCRIPTION

Wow! this Investigatory Project was of the year 2005, and I just saw it now again! I'm so happy that I still had a soft copy of this, this actually helps, reaaallyy :)This is our Science Investigatory Project back when I was 1st year high-school, it's about killing termites or ants with the use of pounded chili pepper extracts. This is really true, after you pour everything to the ants, how in the world will they be able to survive? :)Have fun, hope you can have the idea
