Psalm 78
. . . we will tell the next generation the praiseworthy deeds of the LORD, his power, and the wonders he has done. .
so the next generation would know them . . . and they in turn would tell their children.
Then they would put their trust in God and would not forget his deeds but would keep his commands.

Putt Putt Boats, Part II

We continued our work on making putt putt steam-powered boats. After making vegetable-oil lamps to heat our boilers, we tested the little engines in a dish of water. Sure enough! It wasn't long before we heard a happy little putt-putt sound and the engine jumped in my hand.




Here we deviated quite a bit from the step-by-step instructions from Sciencetoymaker.org and the kids got creative with their hull design. It is advised to secure your heat source better than we did (our vegetable oil dripped and things got a little greasy).



Lane's hull used the pattern from sciencetoymaker.org:
