109
OTTS
112
OTTS
The pen emits infrared light which is a different than the visible light emitted from the
projector. The Wii remote is an infrared camera that will only capture infrared radiation
from its environment; therefore, the Wii remote will only pick up a signal from the infrared
stylus.

OTTS
6.7 [mi/hr]
34 What are MSDS used for?
144
OTTS
1. Answers vary.
2. Most common answers are: Creates desertification like in the Dust Bowl and decreases
food production because the nutrient rich soils are missing from the soil over time if they
aren't replenished.
What is one way to prevent erosion?
1. Answers vary.
2. Common Answers: Plant more trees and vegetation, build rock cliffs and/or rock walls,
put up barriers in the ocean, have impervious material around the water to prevent runoff
and stay on the trail while hiking.
27 Why does the Nintendo Wii remote only pick up signals from the stylus/pen and not get
confused by the projector's image and light?
Material Safety Data Sheets (MSDS) are the standard way of communicating how a
chemical should be handled, including storage recommendations, reactivity, flammability,
and health risks.
