it is a physics device i dont know about.
you don't
The unit works by energising an electromagnet which pulls a stylus down onto a carbon disc and thence through to paper tape. The unit produces 50 dots per second and from the resulting pattern the velocity of the tape may be calculated. The standard ticker tape timer operates from 6V ac and derives its timing from a half wave rectified signal. The universal unit operates from 6V ac or 12V dc. The timing signal is produced electronically within the unit.
Ticker tape was used for telegraphs. The ticker tape would record the information which would then be transmitted through telegraph to the requested parties.
Stock ticker tape is tape used to fix stock tickers. I'm sure you've seen how damaged tickers can get. Stock ticker tape is perfect for repairing and keeping them together.

The first ticker tape machine was invented in 1856. -Wikipedia
Our basic ticker tape timer is AC synchronous, producing dots at precise intervals every 1/60thsecond making precision measurements possible in all kinematics experiments. The body is finished. And requires a 6 V AC or 110 V AC source. Supplied with one roll of 13 MM x 154 MM and package of carbon disc.
Ticker tape is the written communication that was made better in the year 1867. Ticker tape is digital electronic communications.
If you are looking for ticker tape to throw as confetti, you can find it at party stores such as Party City or online at sites like Amazon.com. You will more than likely need to inquire about confetti as ticker tape is no longer used.
