I am not aware of any curling irons that come with video instructions, however, the internet is a great place to download or watch How-To videos for any of your needs, including using a curling iron.
in the middle ages in Scotland
In 1938 there were no curling irons that were electric. They won’t come out until the 1970’s.
they went from rocks to metal
Curling is an Olympic sport with four players on each team where players slide heavy granite stones. The term throwing your hammer in curling means having the last shot at the end.
Le curling (masculine noun): J'aime le curling (I like curling) Du curling: j'ai fait du curling (I played curling)
Curling irons are used to curl the hair. They come in a variety of models, but usually have a barrel and clamp.
A curling sports field can go as low as 0 degrees Fahrenheit. It all depends on how cold it is outside and if the arena has a way of a good amount of air to come in. Olympic curling arenas are much more controlled when it comes to temperature.
Curling...Oh, how I hate Curling. :P
If you mean 'curling (your hair)': Are you curling tonight = Ensortijas anoche? If you mean the game of curling (on ice), there is no Spanish equivalent, so you'd have to say: Juegas a 'curling' anoche = Are you playing at 'curling' tonight?
The most widely-held view is that the Scottish invented curling, so most people would say the Scottish invented the curling rock. Modern curling rocks are much more consistent in terms of shape and weight, but they all come from the same special granite quarry in Scotland.
the main pieces you need for curling are a good pair of curling shoes, curling gloves, a slider for your shoe, and a broom, the rocks are provided by the curling arena.
