After three days, we had some big holes in our shells, but I still needed to rub (easily) the remainder off of the naked egg. The "insides" probably could have used a little more time in the vinegar, but my observers were in fact losing their patience. Here are our naked eggs...cool, right?
Seeing as we had made three naked eggs, we decided to try three different things with them. We put one in corn syrup and it deflated a little bit, but nothing like we thought it would (and the results didn't photograph well either). The second went into water and red food coloring. It got huge...and bright red!
The final egg was taken outside and submitted to some drop-testing. We started out at 3 inches from the ground and increased the height incrementally. That egg bounced pretty darn well, but met its demise at Jack's knee level.
This was such a fun (and easy, no-cost) project! It also inspired a lot of conversation about the science behind the fun (like why was only the outer layer of the egg changed by the vinegar?). If you have some extra eggs in the fridge, this is a great way to use them!
Thinking you should video Jack commentating these awesome experiments and post them on YouTube. I have a feeling they'd be VERY popular!
These were pretty cool. I never held a naked egg before. The red one looked especially neat. Although the 3rd picture is kinda freaky. It looks like a hand is trying to push its way out.
