Today is quite a free day since 3A and B are out at SP. Met a guy from this company where they have this device to teach about air pressure. Pretty neat. The 'toy' could demo how water can boil under 100C when air pressure is low or inflation of balloon. Going to buy a set for physics teachers to demo.

Manage to complete preparing a test... phew.

Karis is down with flu... sad. Woke up a few time since she slept till now. Sigh. Pray that Zuriel will not catch it. Tomorrow will be at Orchard Hotel for a whole day course. Shopping time? Nay.. probably no time.
