Nothing. Play continues as if they hadn't.
It is know as 'bowled'
Not in one of the categories above (Basketball, Billiards, Bowling at time of writing.) No, you are bowled out in Cricket. It is when the ball hits the stumps & dislodges the bails.
But the bails must be dislodged.
As specifeid in Cricket Laws of Marylebone Cricket Club(MCC),cricket stumps are 28 inches (71.1 cm) tall and they are positioned so they are 9 inches (22.86 cm) wide.Two wooden bails are placed on the top of stumps.The bails must not project more than 0.5 inches (1.27 cm) above the stumps
6 stumps and 4 bails. One on each side of the pitch. 3 are allined and on top of them are 2 bails. This is the same on the other side of the pitch.
Cricket bails are typically made of wood and have standard dimensions of 4.5 inches (11.4 cm) in length. Each bail has a diameter of about 1 inch (2.54 cm) and is designed to sit on top of the stumps, with a height of approximately 1.5 inches (3.81 cm). The bails must fit snugly between the three stumps, and there are usually two bails used for each set of stumps.
if you're talking about cricket they are called bails
it is usually ash as is found in ordinary stumps which don't spring back because most woods cannot withstand the force of a cricket ball striking them. However for spring back stumps which are purely models such as DT projects cheaper woods such as pine are acceptable but will be unable to withstand the force of a proper leather cricket ball.
The total height of the stumps including bails is 28.5 inches (720 mm)
Bails. These are short pieces of wood, normally turned on a lathe to give them pleasant curves. The stumps have small grooves in the top and the ends of the bails sit in the grooves so that the wind or whatever would not blow them off. There are two bails on each set of stumps resting on the outer stumps and the middle stump. They are a simple device to show whether the ball hit the stump, even a tiny amount, as if the bail falls off the batsman is out.
The stumps are three vertical posts which supports two bails. The stumps and bails are usually made of wood.Each stump is 28 inches (71.1 cm) tall with maximum and minimum diameters of 1½ inches (3.81 cm) and 1⅜ inches (3.49 cm).
A minimum of 12. They are: 6 stumps - 3 on either side of the pitch 4 bails - 2 on each of the 3 stumps 2 cricket bats - one per batsman
