Opus Book Test English by Denis Marc ParetThis gem of technology, it's an INTELLIGENT MARKER that will allow you to perform miracles. Imagine the following: You are presenting two books to the public. A dictionary of more than 1100 pages (For each language, the number of pages may differ from country to country). A novel of about 300 pages. The viewer chooses a book. You ask him to open this book to any page and give you the page number. IT IS VERY IMPORTANT TO UNDERSTAND THAT THE SPECTATOR
This gem of technology, it's an INTELLIGENT MARKER that will allow you to perform miracles.Imagine the following:
You are presenting two books to the public.
- A dictionary of more than 1100 pages (For each language, the number of pages may differ from country to country).
- A novel of about 300 pages.
IT IS VERY IMPORTANT TO UNDERSTAND THAT THE SPECTATOR MAY BE OVER 30 METERS FROM YOU AND YOU NEVER HAVE THE BOOK BETWEEN YOUR HANDS.
The marker will immediately indicate the first word(s) of the page.
- You also announce a line number. This line number is indicated by the marker which also gives you the first word or words of this line. The lines are all different -- they have been inserted randomly.
- You can immediately announce the same things on the next page.
- You can go from page to page until the end of the book if you wish.
- Each time you will know what to answer.
- If he wants to trap you by giving you a non-existent number, you will know it.
- If he wants to trap you by giving you an empty page number, you'll know it.
- Indication of the marker: An LED light will come on to let you know that the marker is on.
- The choice of book 1: a red led will light up.
- Just by pressing a button, the choice of the book will change, and the blue LED will light up.
- You can skip pages simply with a button to go from 127 to 128 for example. When you are on a page, you can ask for a number between 1 and 10. If the spectator says, for example, 9, they advance 9 pages and you immediately have the same info.
If you want one or two books that belong to you, it will be possible with a supplement.
If you want to write the words yourself, there will be just a very minimal cost in this case.
You can choose to take our dictionary but change the book.
You can use this gimmick in close-up. Nobody will see anything.
- Neither the buttons nor the lights.
- It recharges in ink (ink provided).
- The battery recharges on PC or sector.
- The books are included.

- An online manual is provided.
- An explanatory video is provided (Vimeo link).

3.5, Not 3.0
Color: Medium Set of 6
These balls were almost exactly what I needed. I was replacing my boy’s favorite ball, which is the 3” squeaky, spikey ball that fits in the chuck it launcher. Unfortunately I saw the shiny object next to it and because there were SIX balls and a dollar less, I failed to see that these are 3.5” balls instead of 3”…. Great balls but no fitty in the slingy. Buyer beware. No chuck it no problem. Save a buck.

MY CHIHUAHUA LOVES THESE BALLS!!
Color: Samll Set of 8
My little chihuahua, BamBam, is addicted to balls, especially little balls that squeak! However, any balls that have material on them, BamBam will tear them apart, swallow the material and then get an upset tummy! These balls saved the day! BamBam LOVES them & she cannot tear them apart! They hold up so well! No matter how much BamBam plays with them, they keep squeaking away!
