nearly the end of the second week of school.
time flies.
the second week of school is sure tiring.
maybe my body still not adjusted to long hours of schooling.

wed we did something very interesting.
make rollercoasters!
i'm serious.
but.
we used cardboard and straws.
my group mates were funny.

we were so happy when the marble could roll on our rollercoaster.
super funny.
we were like.
WOW!
haha. xD

we spent nearly 2 hours making something that lasted for 2.2 seconds.
HAHAHA.
the ending point of our rollercoaster?
the rubbish bin!
:D
sounds kind of wasteful but the process was super fun!
