The Oort Cloud...and Comets too!

Below: Map of the Oort Cloud

The Oort Cloud - not to be confused with:

"Our Remaining Tidbits"

...as in the Merrowvista "O.R.T. report"

"Ooh, Aah, O.R.T. Report, I say Ooh, Aah, O.R.T. Report, Woo, Woo."

Above: Jan Hendrik Oort, (1900 - 1992), Dutch

(He discovered the Oort Cloud in 1950)


FYI - Comets are nicknamed:

"Dirty Snowballs" or Long-Haired Stars."

Comets were historically believed to be bad omens:

(If a comet appeared in the sky, then bad times were coming.)

FYI: The "tail" of a comet always points away from the sun.

Parts of a Comet: Coma, Nucleus, Head, Dust Tail, Ion (Gas) Tail

Comets move in highly elliptical orbits as shown above.

1. Dry Ice is solid, frozen carbon dioxide: (CO2)

2. Dry Ice doesn't melt, it sublimates:

(solid --> gas or gas --> solid)

3. Dry Ice is COLD:

(-110 degreees Fahrenheit and -79 degrees Celsius)

4. Dry Ice is colorless, odorless and non-toxic.

5. Dry Ice is heavier than air.

6. Dry Ice will extinguish a fire / flame.

You can purchase Dry Ice at:

Lake Boon Ice Company

70 Main Street

Hudson, MA 01749




Comets are made of frozen Water and frozen Carbon Dioxide:

Just add sugar and flavoiring...

Water + Carbon Dioxide > > Carbonic Acid
