8. Conclusion

9. Conclusion
The heat source expands the air - some of which then escapes from the bottle.

10. Conclusion
The egg seals the neck of the bottle

11. Conclusion
The heat source goes out and allows the air to cool.

12. Conclusion

13. Clean up.

14. Clean up. Wipe clean the neck of the bottle.
Tip the bottle upside down.

The contents are ejected.
This uses the same science - but instead of heat, the energy is provided by my lungs.
