JANGAN MENCARI TERLALU SEMPURNA (DR.FADILAH KAMSAH)

BUAT PEDOMAN BERSAMA.

Jika kamu memancing ikan.... Setelah ikan itu terlekat di mata kail, hendaklah kamu mengambil ikan itu.... Janganlah sesekali kamu LEPASKAN ia semula ke dalam air begitu saja.... Karena ia akan SAKIT oleh kerana bisanya ketajaman mata kailmu dan mungkin ia akan MENDERITA selagi ia masih hidup.

Begitulah juga ......... Setelah kamu memberi banyak PENGHARAPAN kepada seseorang... Setelah ia mulai MENYAYANGIMU hendaklah kamu MENJAGA hatinya.... Janganlah sesekali kamu meninggalkannya begitu saja.... Kerana dia akan TERLUKA oleh kenangan bersamamu dan mungkin TIDAK dapat MELUPAKAN segalanya selagi dia mengingatmu....

Jika kamu menadah air biarlah berpada, jangan terlalu mengharap pada takungannya dan janganlah menganggap ia begitu teguh.... cukuplah sekadar keperluanmu.... Apabila sekali ia retak.... tentu sukar untuk kamu menambalnya semula.... Akhirnya ia dibuang.... Sedangkan jika kamu cuba memperbaikinya mungkin ia masih dapat dipergunakan lagi....

Begitu juga jika kamu memiliki seseorang, TERIMALAH seadanya.... Janganlah kamu terlalu mengaguminya dan janganlah kamu menganggapnya begitu istimewa.... Anggaplah dia manusia biasa. Apabila sekali dia melakukan KESILAPAN bukan mudah bagi kamu untuk menerimanya.... akhirnya kamu KECEWA dan meninggalkannya. Sedangkan jika kamu MEMAAFKANNYA boleh jadi hubungan kamu akan TERUS hingga ke akhirnya....

Jika kamu telah memiliki sepinggan nasi... yang kamu pasti baik untuk dirimu. Mengenyangkan. Berkhasiat. Mengapa kamu berlengah, cuba mencari makanan yang lain.. Terlalu ingin mengejar kelezatan. Kelak, nasi itu akan basi dan kamu tidak boleh memakannya. Kamu akan menyesal.

Begitu juga jika kamu telah bertemu dengan seorang insan..... yang pasti membawa KEBAIKAN kepada dirimu. MENYAYANGIMU... MENGASIHIMU... Mengapa kamu berlengah, cuba MEMBANDINGKANNYA dengan yang lain. Terlalu mengejar kesempurnaan. Kelak, kamu akan KEHILANGANNYA apabila dia menjadi milik orang lain Kamu juga yang akan MENYESAL....

MICROWAVING WATER!!

Microwaving Water!

A 26-year old man decided to have a cup of coffee. He took a cup of water and put it in the
microwave to heat it up (something that he had done numerous times before). I am not sure how long he set the timer for, but he wanted to bring the water to a boil.. When the timer shut the oven off, he removed the cup from the oven. As he looked into the cup, he noted that the! Water was not boiling, but suddenly the water in the cup 'blew up' into his face. The cup remained intact until he threw it out of his hand, but all the water had flown out into his face due to the buildup of energy. His whole face is blistered and he has 1st and 2nd degree burns to his face which may leave scarring.

He also may have lost partial sight in his left eye. While at the hospital, the doctor who was attending to him stated that this is a fairly common occurrence and water (alone) should never be heated in a microwave oven.
If water is heated in this manner, something should be placed in the cup to diffuse the energy such as a wooden stir stick, tea bag, etc..., (nothing metal).

General Electric's Response:


Thanks for contacting us, I will be happy to assist you. The e-mail that you received is correct. Microwaved water and other liquids do not always bubble when they reach the boiling point. They can actually get superheated and not bubble at all. The superheated liquid will bubble up out of the cup when it is moved or when something like a spoon or tea bag is put into it.

To prevent this from happening and causing injury, do not heat any liquid for more than two minutes per cup. After heating, let the cup stand in the microwave for thirty seconds! Before moving it or adding anything into it.

Here is what our local science teacher had to say on the matter: 'Thanks for the microwave warning. I have seen this happen before. It is caused by a phenomenon known as super heating. It can occur anytime water is heated and will particularly occur if the vessel that the water is heated in is new, or when heating a small amount of water (less than half a cup).

What happens is that the water heats faster than the vapor bubbles can form. If the cup is very new then it is unlikely to have small surface scratches inside it that provide a place for the bubbles to form. As the bubbles cannot form and release some of the heat has built up, the liquid does not boil, and the liquid continues to heat up well past its boiling point.

What then usually happens is that the liquid is bumped or jarred, which is just enough of a shock to cause the bubbles to rapidly form and expel the hot liquid. The rapid formation of bubbles is also why a carbonated beverage spews when opened after having been shaken.'
