Eli’s theory of flight

Eli has borrowed a book about paper airplanes from school. So he has had flight in his mind. Today I found this paper on the table. At first I thought he might be working on Chinese at school. But then Parke explained that it is Eli’s theory of flight. More accurately, the drawing is three free body diagrams of three different paper airplanes.

If you look closely, you will notice the wings of the airplane with little L’s above the wings and a G below the wings.

L = lift
G = gravity

According to Eli, when the lift is stronger than the gravity, the plane flies.

Pretty darn accurate.

Tech Night at the Ann Arbor Hands on Museum

We went to a fun event at The Hands on Museum tonight. The local tech community put on a Tech Night. It featured many of the local tech companies and was a great way to learn more about some of the interesting things these companies are doing. But it was really a fundraiser for the museum.

Parke and I took Eli while Oliver stayed home with his Nana. It reminded us how much simpler things are with one kid vs. two. The highlight of the night was a scavenger hunt. Eli was actually quivering when he found the last treasure. It was great to see the museum without all the crowds. Hopefully they’ll do something similar again next year.
