The practical i have these far!

for 2 weeks already i haven post anything interesting. lol.. well, nevermind.. i have my practical today and is the best practical i ever have among all 4 practical i have, last week practical is very relaxing and is biology practical. well, is only about osmosis and diffusion of water from higher concentration into the lower one. is extactly the same as the one i learn in form 4/5? i forgot.. anywhere, is actually a long dull practical because of what we have to wait for the time the osmosis occur and it took me almost 2 hours to finish it. but is relaxing.


the dialysis bag with egg in it. NOT EASY to do it without breaking the egg yolk!


the potato which we are waiting to have osmosis occur!


the egg that we wait for 1hour for the water level to rise!

this week is chemistry practical which is my most fastest practical i ever have. finish the experiment is faster than the question. haha.. but is quite fun and interesting to see all those hydogen gas release when reach.. but is just a small amount and we wont allow to burn it to see some explosion though. crap.. haha..



hee.. shaking for the Mg to reach completely with H!


the burrette that have MG and HCl..

cold weather here lately.. eventually freezing at night.. until i am lazy to even get up and walk around, not to say studying. too cold till it make my favorite routine become a disaster. which is sleeping.. at first, i thought sleeping is a pleasure but now, sleeping is a problem.. haizzz...,
