Yes...am veri happy that our holiday has extended for a week due to H1N1 but very sad to say is we still need to do self learning at home..=( Met up teammates for the P.D project session. We are supposed to do a parachute using a tennis ball and the objective is to see how long can the parachute stay in the air upon dropping it at 3 storey high.

Plastic bag act as conical-shaped canopy

String used to attach the plastic bag.

By using tennis ball as a weight.

Summary:

First we cut the string into 3 of the same length.

Secondly we use 2 of the strings to tie a knot on both side of the plastic bag handle.

Next we tied the 2 strings together and used the other string to attach onto the knot of the 2 strings.

Lastly, using the single string attached with the 2 strings, we used it to tie around the tennis ball tightly as to prevent the ball to slip off.
