Can budgies hover as such? I thought that was more a hummingbirds territory?
Was the cage in first class? Or cattle?

Just experimented on our youngest, with tragic results......

The budgie can hover as he is holding onto a helium baloon thats also in the cage. A vital point i failed to mention.

Aaaaaaargh that has just messed with my head.
(googled the answer)

downshep, i applaud your efforts to try and maintain a 'normal' life for your daughter, but being a man its evident you've chosen an odd pair of earrings, yes they're both ducks but if you look closely they're from different pairs.

Heliophile.

next time it could be a balloon's smiley face.
what about the kidnap victim in the boot btw?
Posted 7 months ago # -
The other ducks from each pair were bundled into a cage and conveyered to the airport.....

C'mon aracer, don't keep us in suspenders

Are you expecting marks for your work?
Posted 7 months ago # -
i'd say backwards as well. assuming its full enough of air to float. interestingly, if you went round a roundabout quickly it should also move to the right of the car
ETA : unless the car was on a conveyer belt, in which case slowing the car's wheels wouldn't make any difference

On to the floor as I would have burst the stupid thing.

Is the question how does it move in relation to the world? or how does it move in relation to the slowing car?
Posted 7 months ago # -
As TJ says.
My friend got asked this in an Oxbridge entry exam many years ago. He said forwards and ended up going to Bristol.

Does it make any difference if you've sucked out the helium to make your voice go all funny?

Definitive answer...

Cool ta Milkie. Looks like TJ is right.

This one is even better cos you can compare the balloons:

Not particularly related, but those vids made me think of this:

consider that the boiling point of Helium is (minus)268.93 (°C)
and then take in to consideration the figure 8.93(meters) being the world record distance a unicycle has travelled along the top of a beer bottle.

remove without taking away, those figures, from each other and as if by magic, you have the answer to maths question of the day.
I hope that helps. (and no, I'm not about to tell you the answer to the boiling water question)

If you stand in the aisle of a train doing 100mph and jump, what happens then?
Posted 7 months ago # -
You fly through the air at 100mph and land exactly where you were before, still travelling at 100mph.

You fly through the air at 100mph and land exactly where you were before
How is that possible?Posted 7 months ago # -
Because you were already travelling at 100mph before you took off.
You go straight up relative to the train, but you're flying at 100mph relative to the outside world. And you land straight back down again. Still going at 100mph.

so all the air goes to the front and the helium to the back
The car is full of air. How does the air go to the front?
Posted 7 months ago # -
Given that whilst sitting in a chair spodding you're already doing around 1000mph due to the rotation of the Earth, would you expect to be able to jump in the air and land in Ireland?
(For the purposes of this example, let's assume that you're not in Ireland already).
Posted 7 months ago # -
The car is full of air. How does the air go to the front?
because its heavier than the baloon, and, under braking, the axis of gravity pulls towards the front of the car. Same reason that the baloon rises when you let go of it

But doesn't the earth rotate the other way, so you could jump from Ireland to the UK but not the other way round unless you started from the Atlantic.

no.

x=mc4-speed of car x 22/7 divided by the circumference of the balloon - temperature inside of car. The answer is it bursts
Posted 7 months ago # -
Yes.. balloon moves backwards, cos the heavier air moves forwards and displaces the lighter balloon.
Imagine a container half full of water. You brake, the water moves forwards.. the air in the container moves backwards.
Tch, stay off the forum for one afternoon and I miss the perfect opportunity to be right and subsequently vindicated... took you lot almost a page for someone to get in there.
