where you would
weigh twice as much as you do on earth? Dr Carl C. Clark, space
scientist with the US Navy, could tell you.

Dr Clark rode in the gondola the giant centrifuge at the Aviation Medical Acceleration Laboratory for 24 hours.
As the machine's huge arm- it weighs 42 tons-carried the gondcla in a circle, it develop- ed a gravity twice that of earth.
The scientist, feeling as heavy as if he were in a scaled capsule on the largest planet in the solar system, carried on all the activities of everyday life.
He ate, slept, stood up, made medical examinations of him- self, wrote down his findings and typed some of them.
He felt some dizziness and
nausea which he found was less when he moved his head slow- ly. By the end of the day even sitting caused some faintness.
These experiments show that when we develop an atomic motor that can produce a steady acceleration of 2g (twice earth's gravity) for 24 hours, spacemen can ride these ships.
Such a motor will shorten the time of space flights. This is be- cause a 2g acceleration for 24 hours in a straight line would carry a rocket at 3.8 million · miles an hour, and it would be 45 million miles away from earth by the end of the day.
Using 2g acceleration half- way to Mars and 2g deceler- ation the rest of the way a space ship could get there in 42 hours. This is, of course, much shorter than the seven months of coasting to bring a chemical rocket to Mars, ог even the three months coasting flight of atomic rcckets now being planned.
This same 25 acceleration halfway and 2g deceleration the rest of the way would carry you to the moon in 31 hours, ог across the country in 15 minutes.
Of course, this motor has not yet been developed. Perhaps you will be the engineer who finds out how to build such a machine.

am very keen to have a Chinese pen-pal, and would be grateful if you would help me.
I am 18 years old and will be taking Advanced Level Botany ard Zoology in the summer. After this I will be studying physiotherapy at St Mary's hospital in London.
This centrifuge is used by space scientists to test rocket parts. The machine can whirl a one-ton load at 121 re- volutions per minute. Similar types can spin men around to sce how they react under high gravity conditions.

JEAN Simmons, currently starring in "The Grass is
Greener" at the Lee & Princess with Cary Grant, Deborah Kerr and Robert Mitchum, is an exponent of lovely lips.

"I learned a lot about applying lipstick from the make-up men on my pictures," said. "I noticed, early in my career, how they always cut- lined the mouth with a brush and then filled in with colcur when they had achieved the balanced curve of both upper and lower lips." Jean believes
the in varying colour of her lipstick to suit the changing seasons and the changing colours of her dresses. With autumn she bronze-toned shades, and with the clear, light colcurs of spring and summer. she wears coral and
pastel pinks.

I am interested in singing, sport, | Never wear purple-toned lip-

and ballroom dancing.
I would like to correspond with a boy of about 18-20 if this is possible. I'm afraid I do not know any Chinese and would be able to write only In English.
I am, however, very interested in Hongkong and its people and would be very pleased if you would help me in this
way.

sticks, she warns, unless your teeth are sparkling white. otherwise they will apper yellowish.
Another trick that actresses
cften use is to outline the lips with a dark shade and then fill in with a lighter one. This is very effective for evening wear and if you have a natur- ally beautiful mouth.
If you have lips whose shape you'd
like to change-for instance If you think your upper lip
compared
is too small
with the lower one extend the lip- line
and with your brush, make it the same size as the other.
first
Powdering the lips before cut- lining them is a good tip, if you plan to make a fuller cutline. Also, if you powder them lightly after the application of lipstick. then apply a second your colour will last hours longer. A final touch of cream on the lower lip adds a highlight that is especially good for photographic pur-
poses.
