rickdg28 Posted November 15, 2005 Share Posted November 15, 2005 hey people! I got a little assignment, I have to transport an egg over 50m, using a mechanism without electricity or mayor human interferance Does anyone have any ideas how to do this??? Thanks:-) Link to comment Share on other sites More sharing options...
YT2095 Posted November 15, 2005 Share Posted November 15, 2005 vertical or horizontal? egg intact after or not? Link to comment Share on other sites More sharing options...
Klaynos Posted November 15, 2005 Share Posted November 15, 2005 trebuchet. it might not be intact when it lands... Link to comment Share on other sites More sharing options...
YT2095 Posted November 15, 2005 Share Posted November 15, 2005 if you carved out a peice of expanded polystyrene packaging and fit the egg inside it would make the journey though you`de need about 2 inches thick all around. Link to comment Share on other sites More sharing options...
Skye Posted November 15, 2005 Share Posted November 15, 2005 Maybe have some softer padding inside. And weight it so it lands with the pointy end of the egg downwards. Link to comment Share on other sites More sharing options...

rickdg28 Posted November 15, 2005 Author Share Posted November 15, 2005 Fine idea, we first thought of a water rocket, but the teacher wo'nt allow us to do something like that (good idea about the polystyrene packaging though!) The egg should survive it, and is raw... We thought about a circuit aswell, but it in a mini-ferris wheel, and make it go round 50times, but it must be 1 long rail or something... I'm clueless Link to comment Share on other sites More sharing options...
insane_alien Posted November 15, 2005 Share Posted November 15, 2005 remote control car? just tape the egg on top Link to comment Share on other sites More sharing options...
Sisyphus Posted November 15, 2005 Share Posted November 15, 2005 No electricity. But maybe you could just have a small wheeled cart, and start it on a ramp. 50m is a long way, though. Is it specified whether or not its a smooth surface? Link to comment Share on other sites More sharing options...
Klaynos Posted November 15, 2005 Share Posted November 15, 2005 find a 50m long hill and put the egg in some form of sphere... Link to comment Share on other sites More sharing options...
rickdg28 Posted November 15, 2005 Author Share Posted November 15, 2005 We can do it in the corridor, so smooth. Would putting it in a cart, and firing it with an electromagnet work? or wouldn't it give enough power? Link to comment Share on other sites More sharing options...

YT2095 Posted November 15, 2005 Share Posted November 15, 2005 if you have the egg securely packaged, it doesn`t matter How tidy you really do this as long as you win! Right? have you considered Compressed gas such as CO2 canisters (the sort used in home made soda pop) on a roller skate, or even a long piece of wood across the hall with 2 pegs and a large elastic between them (Catapault style in a nice arc through the air)? and no, electro magnets use electricity, so that`s against the rules. trained Gerbils anyone???

Sisyphus Posted November 15, 2005 Share Posted November 15, 2005 The big slingshot is a good idea, but why through the air? Wrap it up in a ball, then sling it along the floor so it rolls and has less chance of breaking. Or just bowl it! Is that cheating? Link to comment Share on other sites More sharing options...

I like this idea, you could get 50m easily. Link to comment Share on other sites More sharing options...
rickdg28 Posted November 15, 2005 Author Share Posted November 15, 2005 Alright, thnx everyone I think we'll try the trebuchet using the polystyrene packaging, or the CO2 car Thnx a lot, you were of great help, I'll make some designs, hand them in, and if possible, make photo's and post them in a new topic somewhere Thnx again Rick Link to comment Share on other sites More sharing options...
MattC Posted November 15, 2005 Share Posted November 15, 2005 Send it sliding across an ice rink or frozen over lake! Toss it into 0 g space, let it drift for ages! Link to comment Share on other sites More sharing options...
Callipygous Posted November 15, 2005 Share Posted November 15, 2005 you need a good trebuchet to get that 50m... if it were just an egg it might not be as hard, but you have to get the egg plus enough padding that it doesnt break after being hurled into the air by a medieval siege weapon. good luck with that.

Klaynos Posted November 15, 2005 Share Posted November 15, 2005 Send it sliding across an ice rink or frozen over lake!Toss it into 0 g space' date=' let it drift for ages![/quote'] Where is this 0g space of which you speak? And the packaging shouldn't be too heavy surely? Link to comment Share on other sites More sharing options...
Phi for All Posted November 15, 2005 Share Posted November 15, 2005 Would anything in the rules preclude pulling it to its destination? How about 25m of linked rubber bands attached to a wheeled vehicle? Might get snaps for original thinking.... Link to comment Share on other sites More sharing options...
Callipygous Posted November 15, 2005 Share Posted November 15, 2005 And the packaging shouldn't be too heavy surely? maybe, but think about what you would have to have for padding to keep an egg from cracking after being thrown half a football field. if not heavy it would probably at least be bulky. i think to throw it that far your going to need a pretty decent sized trebuchet. maybe im wrong : P Link to comment Share on other sites More sharing options...
Externet Posted November 15, 2005 Share Posted November 15, 2005 Do not use polyestyrene foam as packaging. Use sponge instead. Only 50 metres? -piece of cake!- Helium balloons will do it, but there is risk the 50 metres can become 50 kilometres and get the first prize plus too many extra bonuses. A tiny leak with an aquarium hose valve on the helium balloon can be set for shorter distances and a very smooth landing and may need very little protection. If a strict path has to be followed by the rules ot the contest, a second air ballon can provide propulsion to the helium carrier while riding captive on a string from start to goal line.

rickdg28 Posted November 16, 2005 Author Share Posted November 16, 2005 Also a good idea, I'll discuss it with the group, and you'll hear the final result Link to comment Share on other sites More sharing options...
Molotov Posted November 16, 2005 Share Posted November 16, 2005 How about a compressed air launcher, something like a potato gun. Should be relatively cheap and easy to build. Link to comment Share on other sites More sharing options...
