Here, he is telling the kids that the blue balloon is the clean air, the black is the smoke, and the orange is the fire. The balloons are all tied in a cluster while he is explaining this.
Next, he tells them how the fire and smoke rise to the top, but the clean air stays down low.
Finally, he releases the clip and the kids SEE the smoke and fire rise and the clean air sinks to the floor. I think this is SUCH a great visual and I have not seen this done by other firefighters who visited us. (Of course this works because the black and orange are full of helium and blue is full of regular air. I am a visual learner so I thought this was awesome!
Well, that about wraps up my week. I hope you all have a great week. Play some games, eat some snacks, make it fun!
