yay!


today's physics lesson was fun

super duper fun...compared to the other practical lessons anyway


we got to test our thermoflasks today with ....


drumroll please.....





DATALOGGERs!!!! clap* clap* clap* clap* clap* clap*



okay lame..



but our thermoflask lost 11 degrees after half an hour

so quite good already~

considering that its just made out of a can, styrofoam cups and aluminium sheets.

and the science fair today was super fun!


i played with baking soda, alka seltzers( a flat pill, put in water and it fizzle like siao)
vinegar and ENO( fizzy powder, put in water and it also fizzle like siao)

plus a small plastic canister.



first put any fizzy powder and pill into the canister.

then pour water( actually vinegar is better )

and quickly cap it up before it fizzles out of control

turn it upside down

place on the floor


and watch it pop and fly into the air like a rocket... phiiieeeoooowwww....zoomm....crash


and it makes a serious mess when it pops and drops back to Earth, and that i did within free period for half an hour.

so fun! oh and it did make a mess out of my pants, lots of white spots from the fizzy powder mixture splattering, then i later went to toilet to clean the mess on my uniform,
i also accidentally spilled lots of it around the SPACE area.



whoops... keke >.<

well...too bad i did not take any pics while the experiment was on, my hands were too full and wet and i was having too much fun ...grr and i didn't have enough time to revise for the Maths test later on



hope the test results are gd.
