If you’re in #kidmin there’s a good chance that you spend a good amount of your time looking for #objectlessons, #magictricks, or #scienceexperiments. As a presenter you want to find ways to help kids see a concept taught in scripture in relevant and engaging way
Jesus did this right? He took a complicated subject like redemption and put it terms that people could understand, like a father son relationship.
This object lesson is one that I think is a lot of fun and gets kids and adults to lean in for the message. It’s a good thing too because in this particular message I’m presenting the #gospel and #salvation in a clear and understandable way.
I started the talk with a flawless, clear, glass cup. I talked about how when God created the world it was absolutely perfect! But when Adam and Eve broke the only rule God had for them, it broke everything.
With that statement I dropped the glass cup. Be prepared because of the kind of glass you have to use, sometimes it would break and sometimes I had to give it a little encouragement. (Hence the reason I stepped on it).
Every time this happened the audience learned forward. During this talk I was able to talk about how even if I was very meticulous and taped or glued each glass piece back together, there was no going back. Just like how there was no going back with the glass, once Adam and Eve sinned, there was no hope.
Next up in my object lesson I had a large tub of liquid. It’s a very specific liquid that helps pull off the illusion that makes this object lesson so interesting.
In the talk I set up the fact that Jesus lived the perfect life we could never live, and in dying on the cross and rising again, he takes our brokenness and makes it new again. While I say this I add the shards of glass to the tub. Then I pull out a completely whole glass.
Pulling out the new glass gets the audience to lean in again as they see the broken pieces vanish and a new glass appear, seemingly out of nowhere.
So what is the liquid? And how does the science of the experiment work?
Well it’s a very simple (albeit very messy) object lesson. Essentially the liquid, Wesson vegetable oil, and the glass (it’s called borosilicate glass) has an almost identical refraction index.
Essentially when you see things what you are really seeing is light either refracting or reflecting through or off of items. So when the refraction index is the same for the oil and glass light passes through the oil and the glass in the same way; making the glass in the liquid nearly invisible.
The whole glass that I pull out at the end is in the vegetable oil the entire time. When the broken glass goes in it becomes hard to see and I simply reached in and removed the whole glass.
Keep in mind a pair of rubber gloves might not be a bad idea (especially since you are dropping in broken glass that becomes almost invisible).
I hope this object lesson is helpful. The type of glass is very important. Borosilicate is sometimes referred to as pyrex glass. It’s used a lot in education and science arenas. We did order some Pyrex branded glass and it did not work. The index was enough different that the glass was very visible in the oil. The glass I used in the video you can find on amazon here.
We used the object lesson to represent salvation and redemption but there’s certainly other ways and applications in which you could use it.
