This is the last day of their week long trip. Grandmother, W.H., Aunt Allison, Uncle Mark and Harrison's flight was a lot earlier (and longer) than Mom and Dad's flight. After dropping them off at the airport and saying their goodbyes, Mom and Dad decided to spend the morning at the Leonardo D
aVinci exhibit in Balboa Park. Grandmother and W.H. went the day before and talked about how interesting it is, making Mom and Dad think that they might enjoy it too.
When I hear the word "Leonardo D
aVinci", I automatically think about Mona Lisa or the Lord's Supper paintings. After hearing Mom and Dad discuss what all they learned, D
aVinci was not only a painter ahead of his time but also an inventor. Relying solely on materials that were available in the 15
th-century in Italy, he designed various modes of transportation, military warfare tactics, and mechanical inventions.
This airplane glider was one of his most famous inventions, but it is believed that it was never flown. I guess D
aVinci himself and his companions did not trust his designs THAT MUCH to be the first to attempt to fly using this contraption. I do not blame them.
This was the first paddle boat. Everything was made from wood since that was all he had available to him during the 15
th century. He also invented a wooden bicycle with wooden wheels.
This is called the Tank and was Grandmother's favorite.
Basically, it was designed to roll into the enemy's camp with the top down and then fire these canons, surprising the enemy. However, it was flawed due to the difficulty of
maneuvering this heavy wooden machine and the people firing the canons would have become deaf since they are so close in proximity. I guess even the best of inventors still do not always think things through sometimes.
Leonardo D
aVinci also came up with ways to make work easier and machines last longer. He is the one who thought of using a pulley to lift heavy loads and three-ball bearings to decrease friction caused by objects rubbing together, preventing machines from breaking down over time.
This robot was Mom's favorite design. It has the ability to anatomically correctly open and close it's jaw, sit up, wave it's arms and move it's head by the use of hidden pulleys. The robot was probably used to entertain D
aVinci's royal guests. I would have been entertained (more like scared) by it, especially during the 15
th century.
All of this education made Mom and Dad hungry so they decided to go back to the Gas Lamp District for lunch. As they ate sandwiches, they enjoyed people-watching and the wonderful 70 degree weather.
Then, Mom and Dad decided to see some of Downtown San Diego's waterfront.
They enjoyed watching all of the activity on the water and then took a nice little nap in the car, relaxing with the cool breeze.
During a short flight, they could see Sacramento's skyline. Mom said this is the only way to see the skyline because the land is completely flat. The only "hills" are going up the
interstates overpasses.
The plane landed at 7:30 pm and Mom and Dad stepped outside in the
stifling 102 degree weather. They described it as walking into an oven.
They missed me so much they came by my doggy hotel to pick me up before they went home. I was sure glad to see them and definitely missed my chair.
