Balloons

Helium

Helium is inside balloons and makes them rise in the air. Helium is lighter than air.

Element Uses:1. Cool magnets in MRI scan2. Lift baloons into the air. Helium islighter than air.3. Used to make air transport as in the zepplin.4. Used to condense hydrogen and Oxygen to make rocket fuel5. Added to oxygen tanks so divers can breathe more easily. 6. Used in Helium - Neon lasers to read bar codes.7. Helium dating for the age of rocks.8. Detects leaks in Vessels

Cool Facts:1. 6,000 balloons filled with helium can lift a child that weights 75 pounds.2. It's tastless and has not odor. 3. One of the oldest elements.4. Second lightest element in the universe.5. Helium comes from the Greek word Helios meaning sun.6. The second most abundant element. 7. Used as a life saving anesthetic for people suffering from SEVERE asthma.8. In cryigenics, it's used to freeze and store biological materials.9. Used as a cooling agent for cooling plants.10. Non-Flammable11. Instead of freezing, Helium becomes a super fluid at -271*C (-445.8*F)
