You will be launching an egg from a table to the floor. Your mission is to design an egg-protection vehicle – protect the eggs at all costs! Build a vehicle that will protect an egg in free fall from the highest point available.
There's not much dangerous here but watch out for:
- Broken eggs are a slip hazard – clear up any breakages as soon as they happen – the only thing we don't mind getting broken are eggshells.
- You may need to stand on a chair or a stepladder to reach the very highest drop zones – if you do, make sure you ask for an adult's permission and get them to supervise.
Make a vehicle that can hold and protect a raw egg when the vehicle drives over the edge of a cliff.
Make an egg-sized nest in the middle of the vehicle and try to get the egg nice and snugly set.
Take your eggtastic vehicle to the edge of the cliff (a low level coffee table will do for starters) and roll it over the edge.
Check to see if your egg survived intact.
If it did you can test it from a higher level – try a kitchen work surface for example.
If it broke then you're on clear-up duty before heading back to the drawing board to try and improve your design.
Keep going till you've either successfully tested your vehicle from every high surface you can find (well done!) or you've broken every egg you mother allowed you to use (oops!).
- If you're doing this activity with younger children you can tell them that the eggs contain a knockout nerve gas and that the slightest crack in the shell will poison you all. You can put some real amateur dramatic fun into getting knocked unconscious by the gas when it escapes.
- Use old newspaper and perhaps some bubble wrap to really wrap up your egg – test it from the highest points you can to really find out how good a job you've done.
- Set up a competition with friends. Everyone gets two eggs, and you take turns to launch the vehicles (one egg at a time) from higher and higher tables. You lose a life when an egg breaks, and when both eggs are broken, you're out of the game.
- Take pictures of your testing – get your parents to share them on Freaky Rivet's Facebook page.
- Try to create an ultra high speed series of photos showing your vehicle crashing to the ground. Only some digital cameras will have this functionality. Going on to use some graphics software to make an animation would be awesome.
Try to build in a crumple zone into your vehicle – these are used in all modern cars to dissipate the forces in collisions. The idea is that the crumple zone will crumple and the egg will take less of a knock as a result.
