Ryan,
KS | How to measure
rainfall?
Does anyone know how a meterologist measures rain? We just did an
experiment with different size rain catchers to figure out how to
measure rain. We got different results with each rain catcher, measuring
in inches and in ounces.

Hi! I am not sure what you are talking about, but I'll tell you
why I think thunder makes so much noise. Did you know that lighting
comes before thunder? See why you hear thunder is because of friction
of the clouds rubbing agenst each other. I may not be right on any
of this, but it's worth a shot. bYe! LuCy

Storms...
Well, I love thunder storms, sea cretures,snakes, and sports. I
wanted some ideas on a great investigation. And I might need some
help.

Dear kids,
I just want to tell you that weathering and other stuff is sweet.I
hope the kids will like weathering when thay get older.

I wanted to find out where the professor named Howie taught at.
I saw that program today where he chases tornados. It would be great
if he's from where I'm going to college because I'm planning to
major in meteorology!

Robert, 12, NC | Another
way to make a tornado
I think you could make a tornado in a diffrent way. Use a humidifier,
an air conditioner, & a clear tube/box with sand in the bottom.
1.) somehow get the vents of both the warm humidifier & the
air conditioner to send air only into the tube/box.
2.) seal off each end of the box/tube you directed the vents through.
3.)cut a few slots in the top of the box/tube about big enough for
2 or 3 nickles to fit through.
4.) turn on the humidifier and air conditioner to low.
The hot moist air from the humidifier, should mix with the dry cold
air from the air conditioner, making a tornado. The sand the mini-twister
should pick up is supposed to make the funnel visable.(you may need
to put a fan on the little slits in the top to help form the tornado.)This
should theoretically work, considering this is how most natural
twisters form. You may need to vary the the setting on the AC and
humidifier to achieve the F0.0000 whatever tornado.

I have a question about your tornado model that was made on the
show. Where exactly was the placement of the fans? My son was trying
this experiment.
DragonflyTV | Make
a tornado response
I'll admit that I tried making my own tornado, too, after watching
Sullivan do his... it is not easy! To place the fans, put the top
fan over a hole in the center of the chamber. As Sullivans' results
indicated, this fan is crucial to getting a good vortex. The stronger
the fan, the better, and of course, make sure it blows UP, not down
into the chamber. The side fan is less critical, but I would aim
it into the chamber at a side wall, not right through the center
of the chamber, and I would start with a low setting. This fan only
needs to nudge the air in a sideways direction... some tornado models
don't even use a side fan, just some side vents. Again,
I think the most critical thing is to get a good strong updraft
fan. Good luck!!

Experiment Ideas
I am trying to find out more about the tornado experiment done on
March 2nd, on dragonfly tv. Can you help? Sullivan and Alexa did
a fan experiment and I would like to know how they did it. Can you
give me more details on their experiment or will the show be replayed
where I can just view it again.

The best thing to do is to look at the Explore DFTV link on the
left of this page. Select the Weather show, and click on the button
for Tornado model. You can read about Sullivan and Alexa's experiment
there.

My question is where can I find the experiment of a tornados vortex

A description of that investigation is found in the Explore DFTV
portion of our site. You can read about Sullivan and Alexa's work
there. For some detailed instructions on building your own tornado
generator, try Weather

Ryan, 8, CA | Stop
a thief with Tidal Waves
In the episode that explored using a tidal wave for security, I
decided that would be possible. You could have everything you talked
about except for the sharks and paranias. When burglar swims across
the water or moat he wouldn't be able to get in because the door
is fortified like a draw bridge. If the burglar took a boat over
to the house and he tried to climb onto the roof, his body pressure
from standing on the roof would send a message to activate hoses
to push him back into the water.

can you please send me some experiments reguarding how to make storms
with water and or fans?
