Pillar of Salt | Object Lesson

This is an object lesson that can help you teach your class about how Lot’s wife was turned into a pillar of salt!

Needed:

• Small plastic figurines (Lot and Lot’s wife)
• Container of sodium acetate (can be purchased online, often called “Hot Ice”)
• Microwave-safe container or small beaker
• Microwave
• Small decorative container or clear plastic cup for the demonstration
• A few solid sodium acetate crystals (to trigger crystallization)

This object lesson powerfully illustrates the story of Lot’s wife from Genesis 19, teaching children the importance of obeying God and not looking back to the sinful things we’ve left behind. The visual demonstration of sodium acetate turning from liquid to solid “salt” right before their eyes is both fascinating and memorable.

Begin by telling the story of Abraham and Lot. Explain how Abraham pleaded with God to spare Sodom if righteous people could be found there—but sadly, there weren’t even ten. Because of this, God sent angels to rescue Lot and his family before destroying the city. The angels gave one simple instruction: “Don’t look back.”

Show your small figurines of Lot and his wife. As you describe their escape, explain that Lot’s wife couldn’t resist turning back for one last look. When she did, she was instantly turned into a pillar of salt.

Now it’s time to bring the story to life with science. Show the class your container of sodium acetate, explaining that it’s also known as “hot ice.” Tell them that it starts out as a liquid but instantly turns solid when it touches a crystal—just like Lot’s wife instantly turned solid when she looked back.

If your sodium acetate is already in solid form, start by gently heating it in a microwave-safe container for about 30–45 seconds at a time. Stir it occasionally until it’s fully melted into a clear liquid. Be careful—it will be warm, but not dangerously hot. Once melted, pour the liquid carefully into a clean plastic cup or small clear container. The key is to make sure it doesn’t touch any leftover crystals; if it does, it will harden too early.

When you’re ready for the demonstration, take one or two tiny crystals of sodium acetate and place them gently on the “head” of the Lot’s wife figurine. Then slowly pour the liquid over the top of her. Instantly, the liquid will begin to crystallize, hardening into what looks like salt or ice right before everyone’s eyes. The children will see the transformation happen in seconds—it’s as if Lot’s wife froze in time.

Explain that this is what happens when we turn back to our old ways. When we’ve repented and started following God, He wants us to move forward, not backward. Looking back at sin can harden our hearts and stop us from growing spiritually—just like the sodium acetate hardens into solid salt.

You can also explain a little science behind it: sodium acetate is a super-saturated solution, meaning it’s holding more dissolved material than it normally could at room temperature. It stays liquid only because it’s undisturbed, but the moment it touches a crystal—or anything that disrupts it—it instantly solidifies. That’s a great parallel to sin and temptation: as long as we stay focused on God, we remain stable, but when we look back, even a small compromise can harden our hearts.

Wrap up the lesson by encouraging your students to keep moving forward in their walk with God. Remind them that repentance means turning away from sin, not glancing back at it. God has something better ahead for all of us, but only if we keep our eyes on Him.This experiment can be reused many times. Once the sodium acetate has hardened, you can reheat it in the microwave to melt it again, cool it, and reuse it for future lessons. It’s safe to handle, produces gentle heat as it crystallizes, and serves as a vivid reminder: Don’t look back!
