Design Challenge With A Golf Ball

How do i lift a golf ball off the floor to the greatest height possible and transport it to the greatest distance across an existing railway system??

And i can use some of these materials:
mousetrap              pins
straws                      small(1/4---1/4*6)wood
popsicle sticks       elastic bands
hot glue                    juice cans,lids
tape                          screws and nails
other                         string


Someone please help!!!!

What is with all the golf ball questions lately? :-)
sounds almost like a class project to me. is it?
or it there an international golf ball competition or something. :0)

other???
if you can use other (anything):
1) use the hot glue and glue it to the best rocket you can buy at a model shop
2) Launch rocket

You win.
Do not do what I said - your teacher will fail you for sure - but what is other???

Sounds like fun...but using raw eggs for something like this would be more fun - messy even.
> sounds almost like a class project to me. is it?

Well, maybe for someone else, did ya note how the columns lined up so good here?
Interesting answer to this perhaps. For now I (ignoring other) see only advantage in these (how many can we employ, all?

juice cans: Golf balls are very vulnerable to just rolling around anywhere. So these, or just one, can have value in stabilizing the ball, for example so that it does not roll backward on train.

popsicle sticks & small(1/4---1/4*6)wood: these are essentially the same objects, concerning the functions I'd employ. I consider them equal, so try them and pick what suits ya. I'd go with popsicle sticks since they are more familiar and handy to avail some practise.

elastic bands: sounds good, I'll take that as well and call it a day.

hot glue: this makes it too vague, too many options so I'll not use it. Consider that you can glue one popsicle stick to another, Then add another stick. If the available quantity is unbounded, then you can essentially build an infinity of contrivances. So I reject that as possibility, for it leaves the matter too open-ended to be viable as fair question, unless we're merely exercising your imagination, which we of course cannot do that either. That is do it yourself.

Ok, take a guess on me. What would I do with so few? Use imagination!
>>did ya note how the columns lined up so good here?<<

not sure what you mean by that. :0)
Once again - do not do what I say - look at my name for cryin out loud.

: ) Place golf ball in teacher's right hand.
: ) Position moustrap under teacher's left hand - careful so that the release mechanism is directly under fingertips of said teacher.
: ) Slowly elevate mousetrap until release mechanism makes contact with teacher's fingers. As mousetrap Slams shut on fingers of soon to be irate teacher - release mousetrap and run. If you out run the golfball you win.

And for the sake of repeating myself: .....

Once again - do not do what I say - look at my name for cryin out loud.
Can we use our hands or arm strength or pockets? I doubt that, even for an 'other'.

>  i lift a golf ball off the floor

These take but a pair of sticks. More if you are pessimistic or poorly coordinated. Place one on each side of ball, grab and lift it. Lift high over head. That's my offer. One could argue that the wood is longer so you could reach higher. I suggest that as it is less familiar, you're more likely to drop it before you can get it as high as with good old popsicle sticks. They are also more narrow IMO, so while they may do as well lifting ball off floor, they won't grasp as well. Unsaid is whether they are of hard or soft wood, and the difference is extremely important. So, IMO better the given pop_sticks, their flex is a known.

Now you could argue that it'd be easier to drop ball into can immediately after lifting. Sure, that stabilizes it. But it is unnecessary to the problem. Besides, if you lift can normally, the ball is at bottom, going no higher that your oustretched hand.

Possibly, if in a hurry and not expert, a small dab of glue on the sticks may improve the grip. Depending on glue, it may also make sticks more slippery. When in doubt, leave it out, for it is not needed.

> and transport it to the greatest distance across an existing railway system??

So tak it to train. At end of line give it a toss to increase lateral  distance. Take elastic band and make slingshot with the sticks. Maybe even do a discuss toss move, and propel it with additional push from the elastic.

The end.

While nails, tape, glue, pins, etc may make for an improved slingshot, such use has same problem as one arose before. For one they are not needed, and for two, once you start permitting an open ended building excersize, the whole point of question is gone. Suppose I said I'd build a ramp of sticks to Jupiter or Andromeda? Such an answer must not be permitted.

* Real answer is pick up with hand, toss ball up and bounce of ceiling, catch it and take to train and throw it forward (direction of train movement. Your hand is needed to use the contrivances you've listed anyway, so it really cannot be left out of question no matter what you say. My opinion.
Use the mouse trap and build a tiny catapolt.
No idea how to spell that, not a word i use every day in the IT industry.  Maybe it should be.  "Bob what should we do with this server error"

me: "well sir, i say we use a catapolt"

Search "MacGyver"

Purchase tape with episodes 37,38 and 39 on it - its the perfect tape!

In ep 37 he had to project a golf ball a great distance across the room using only popsicle stick and an elastic band in order to disable a nuclear weapon.

In ep 38 he only had some cans, popsicle sticks and straws to help him transport a bomb deep into a mineshaft along its railcar tracks.

And in ep 39, the unique way he taped the string to that mousetrap, giving him a quick way to get onto the roof of that tall building -- well without that magnificant feat, he would have never been able to stop the bad guys from releasing the bioagent into the circulation system at the ambassador's banquet.

Between those three eps -- all one one tape too -- you've got most of your supplies and the vertical and horizontal transportation systems.  A shot of whiskey everytime a woman says "oh no, what will we do now", and by the end of the tape, you're inspired.
LOL, MacGyver. Good thinking.

I have a rather simple design that might get headed in the right direction.

Elevating the ball:
The stored energy of the mouse trap or rubber bands could be used to shoot the ball in the air.  Using the popsicle sticks or the wood you can build a nice V slingshot.

Elevation stabilization:
Use the popsicle sticks, wood and glue to build an angled  shaft (a contained ramp) that guides your shot golf ball upwards.  (Like at miniature golf)

Shaft to railway containment:
When the ball is shot up the ramp/shaft it will fall into a tin cup attached to the string railway.

Railway transport:
The tin can should be lightly attached to the string railway such that once the weight of the ball is added the tin can slides down the string with the ball inside.  Maybe stick a little tape on the string to hold the can in place until the ball falls in.  

Railway Transport:
The tin can should be affixed to the string using some type of "pulley" or lanyard.  You need to make something that will have a low coefficient of friction when slid along the string railway.  Probably the best item to make your lanyard from would be a 1/2" piece of a plastic straw.  The string railway will go through the center of the straw and then you can affix the tin can to the straw using popsicle sticks or string.   So in effect your straw becomes the guide for your railway.

I'm not sure how this is going to format, but here goes;
(String should be on an angle towards the floor)

Obviously the higher you can get the ball in the air the more potential energy that is stored and the further the tin can will travel along the string.

Put the ball in the can and tape the lid shut. Place on floor. Call FedEX. Use the rest of the tape and sticks to place fake splints on your hands. When FedEx arrives tell them you'll give them an extra hundred if they send this package to a remote corner of the earth with the last few miles railway accessible only. And it doesn't matter how long it takes to get there as long as it goes on one of their planes that flies the highest.

Go with MacGyver.
"And i can use some of these materials:"

Are the words correct or have you mis-typed? If they are correct then there is no obligation to use any of the materials as it says CAN use not MUST use. In which case just pick up the ball and walk over the bridge over the railway.

Not much of a problem....

call tigar wood
:)
also for the MacGyver lead               :-)
Get Tiger Woods to hit it!
I hope Leighsha didn't get lost trying to find the MacGyver tape, seeing how I goofed - those three episodes are NOT on the same tape...

I bet the class project is over and EE did not win ... leo
