Invention: The "Secret Message Dispenser"
Description: The Secret Message Dispenser is a small, portable device that Tom Sawyer can use to send secret messages to his friends, like Huck Finn and Becky Thatcher, while ensuring that no one else can read them. It looks like a small box, roughly the size of a book, with a few buttons on the front and a small paper roll inside.
How It Works:
-
Paper Roll: The dispenser has a roll of special, thin, lightweight paper inside. When Tom wants to write a message, he simply pulls out a bit of paper from the side of the device.
-
Ink Cartridge: The dispenser contains a tiny ink cartridge filled with invisible ink. When Tom writes his message, he presses down on the device’s surface, which activates the invisible ink to write directly onto the paper.
-
Secret Code Input: There are three buttons on the front:
- Button 1: Sends the message to a specific friend (Huck or Becky) and uses a simple code (like "1" for Huck, "2" for Becky).
- Button 2: Activates a tiny timer that can delay the message until a specific time.
- Button 3: A "send" button that releases the message through a small slot when pressed.
-
Privacy Lock: To ensure that no one else can read the messages, Tom can digitally lock the dispenser with a simple two-digit code (like the day of the month). He just has to set it before sending any messages.
-
Magic Reveal Feature: When the recipient receives the message, they can use a special light (or even just heat from their breath) to reveal the invisible ink and read the hidden message.
Drawing Tips:
- Draw the dispenser like a small box with a roll of paper sticking out.
- Include buttons on the front, labeled with numbers.
- Show a small slot where messages come out.
- Add some design details to make it look "mysterious" or adventurous!
This invention would have definitely helped Tom keep his adventures secret and communicate with his friends without fear of being overheard!
