We've all heard of the classic egg-drop engineering challenge, so here's a twist: crash test race cars! The students in my extracurricular engineering class love this project because of its open-ended nature and thrilling process.

Step 1: Materials and Tools

This list is just an example of materials you can use. Be creative with your selection :)

The presence of obviously soft or resilient materials will often hinder creative ideas.

Plastic Easter eggs will help students gauge how they will need to accommodate a real egg without risk of accident.

Folding tables make excellent ramps.

Fast, easy, and edible hard boiled eggs:
Place as many eggs as will fit in a pot of cold water. Make sure the eggs are covered with at least one inch of water. As soon as the water begins to boil, turn off the heat and cover. Wait 8 minutes. Place eggs directly from the pot back into the carton (most of the moisture will evaporate).

<p>very nice ideas, i'm about to try it out now!</p>

I'm having a hard time thinking of something besides what W'burg has suggested for axles. . Pretzel sticks may be too brittle. Something relatively soft for tires (string licorice?) might absorb enough shock to protect the pretzels. If the ramp isn't very long, it may not be a big deal. . Spaghetti probably flexes enough to work well. Do they make spaghetti large enough? . A carrot stick sounds like something worth trying. If a fresh one doesn't work, try using a dried one. . I'm guessing that sugar will be too brittle and ice just doesn't sound very practical. . . For general construction, I'll add: . Cookies . Decorative icing for glue <br>3NachoMahma in reply to NachoMahmaMay 10, 2009. 7:35 AMReply. Oops! Those were CameronSS's suggestions. I don't know where I got W'burg from (vaguely similar avatars?). Sorry.Ria Hawk says: May 9, 2009. 11:34 PMReplyIf you can get peppermint sticks, they'd make dandy axles, though I have no idea how you'd attatch them. Life Savers would make good wheels, as long as your axles will fit into the holes. So would wagon wheel pasta, if you can get away with uncooked pasta. If you feel particularly adventurous, you could try baking bread/dense cake into the parts...and7barton says: May 9, 2009. 6:30 AMReplyWhy not use macaroni ? - It's a good wide cylindrical shape. But it would need to be cooked to eat it afterwards - So how about &quot;Sweet cigarettes&quot; - If they are available these days. <br>37AndyGadget says: May 9, 2009. 5:53 AMReplyIf you're feeling enthusiastic, you could make a FULL SIZE edible car.

Wow keep this up and you will need a <a href="http://juanlaw.com/truck-accident-lawyer" rel="nofollow">dallas truck accident attorney</a>. Cool beans man.
Did you edit out &quot;non survivors&quot; in the video? Success seems to come a bit too easily here if not. Even eggs that were thrown clear of the crash were &quot;safe&quot;. This is an AWESOME activity, but I want to modify it to be a little more challenging to &quot;survive&quot;.
Very nice ideas, I do something similar with my students , I limit their supplies to:<br> 1 sheet of paper<br> 2 feet of masking tape<br> a rubber band a<br> 3x5 index card<br> 1 1/2 straws (for axil bearings and whatever else)<br> <br> I provide the wheels and axils (the plunger from nestle &quot;push-ups&quot; ice cream)<br> <br> Although I agree with: &quot;The presence of obviously soft or resilient materials will often hinder creative ideas.&quot;...170+ students, supplies get costly. I also make them race each other so that friction also comes into play (another teaching point) and they don't try the &quot;slow role&quot; technique. there is a video here:<a href="http://youtu.be/XqI5H8d4r7M" rel="nofollow">http://youtu.be/XqI5H8d4r7M</a><br> <br> You have some ideas I will incorporate. &nbsp;I need help making the connection (in the kids minds) to newtons laws. &nbsp;I &quot;talk about it&quot; (ho-hum), but I wish I had a piece that assesses the connection.
Nice video! - Are the cars being pulled into the wall with rubberband? They seem to be going quite fast. Love the lane markers and black/white checkered finish line<br><br>Materials do get costly (I also have about 170 students under my program), though I'm fortunate enough to have a $2 budget per student for each project. You could invest in wheels from Kelvin.com and reuse them if you can't afford to let the students take it home. <br><br>In my lectures I don't explicitly state Newton's Laws. Instead I focus on allowing the kids to learn about them by crashing their cars and observing the results; they learn by experience, not verbal definition. Let me know how you decide to incorporate the laws of motion in your next class. Thanks for your thoughts :)
They are on an incline ramp with a trigger start. it starts at about 35 degrees , then finishes at about 15 degrees. <br><br>Thanks for the link to kelvin.com, I have been looking for a source for wheels.<br>
Did the egg-sandwhicher work?
Its cool toy))))) But i like this too: <a href="http://www.vondgroup.ru" rel="nofollow">хозяйственные товары</a>
This is pretty inspirational. An easy way to make a commonplace experiment MUCH more exciting and still grounded in what the kids need to learn. This is awesome.
Exactly! I've done the egg drop with kids, and the big problem is all of the excitement is wrapped up in one moment, which can quickly turn to major disappointment. With this project, if it fails, just rebuild and try again. AND the kids get to take an awesome car home instead of a busted up container :D
This is fun!
V-good, its cute to see how excited those kids were when they launched their cars :)
