Snowball Effect

Grown up at a place wherenever seen snow before, we treat it as a miracle happens. While others had been with snow ever since they are in their childhood age, they will pick up a handful chunk of snow, packed them tightly and throw at someone else.

Therefore, we get what ever kind of reports about people thrown by snowballs, and even snowballs (a large one) was left on the centre of the road blocking the way etc.

Snowballs prompt 500 calls to 999.

and lastly, we have The etiquette of snowball fights.

Well, we all know that snowball fights will occur when snow comes, but we don't know that we may be charged for "Assault" on somebody if we throw one at them, don't we?? Offences Against the Person Act 1861, Section 42 Common Assault and Battery says so. By the time the "evidence" of the assault which is the snowball is brought to the court, if the police or SOCO knew which snowball it is used, it will already melted away.

Deionised Water

Just a short talk about this one, before we start our labs, we have to fill in a form given by the lecturer, just to let us know and remind ourselves what the chemical hazards are, considered as one of the assignments during Christmas break. One of the chemical is "Deionised Water", I am able to fill up all other dangerous chemicals, including some very cool long names such as nickel chloride hexahydrate which will be Irritant if you came into contact with it without gloves on, or oxalic acid dihydrate will be Harmful and Corrosive. But after scratching my head for quite some time, I still don't know what kind of hazards Deionised Water has, just for the joke, maybe in a very large amount of Deionised Water, we may be drown by it, or choke on it when we talk while drinking it, but we are not suppose to consume anything in the lab.

Here is the Material Safety Data Sheet from Fisher Scientific about Deionised Water.
