Discussion Overview

The discussion centers around the construction of a balloon-powered hovercraft using a CD as the base. Participants explore design ideas and modifications to meet specific conditions, including achieving a minimum displacement of three meters without using any electric motors or modifying the CD.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks suggestions for building a hovercraft powered by a single balloon and using a CD as the base, emphasizing the need for specific conditions.
  • Another participant requests ideas but does not provide further details.
  • A suggestion is made to conduct a Google image search for balloon-powered hovercraft, which may provide visual inspiration.
  • A participant mentions that previous searches did not yield satisfactory designs that meet the stated conditions, noting issues with displacement and stability.
  • One participant references a video demonstrating the use of a pull-up top from a bottled water container to assist with displacement, suggesting modifications to enhance thrust by drilling a hole or building up the edge of the CD with glue.
  • Another participant expresses appreciation for the video suggestion and inquires about reducing resistance between the CD base and the floor, specifically on smooth tiles.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the best design approach, and multiple ideas and modifications are being explored without resolution on effectiveness.

Contextual Notes

Participants have expressed limitations in finding suitable designs that meet all specified conditions, indicating a need for further exploration and experimentation.

I need suggestion on how to make a balloon powered Hovercraft.

THE AIM: the aim is to make the hovercraft travell a displacement of tleast 3 meters..

THE CONDITIONS:
1. it has to be powered by no more than a single party balloon.
2. the base of the hovercraft must be a CD. (the CD cannot be modified (cut or shaped))
3. the hovercraft can be modified any way with any material as long as it follows the above conditions. ( the source of powere must be the balloon. so we cannot add an electric motor or something to powere it.)


P.S .. i did search for previous topics related to this. nd i didn't find wat i waz lookin for nd some of the thing didn't make sense to me.. sorry, if u can provide a link to a previous topic related to this, dat wud be gr8.. but i don't think there is a topic wit these exact conditions.. Thanks

Nd I'm new here, so if i make any mistake let me kno please.. nd if i do then i apologize in advance.. thanks

can someone please give me some ideas...
 
tried that... nd most of them doesn't meet the conditions above.. nd i took some ideas from google nd modified it but it doesn't get a gud displacement... most of them just spun out...
 
If you did a Google search on CD balloon Hovercraft then you probably saw the video using the pull up top from a bottled water container. They give the hovercraft a small push to get it to displace. If that is not allowed you will need some thrust from the balloon to get the craft moving horizontally. Try drilling a hole in the side of the bottle top. Some of the escaping air may provide enough thrust to move it horizontally. Or you might try building up the bottom edge of the CD with glue. Leave enough of a gap in the glue edge so that escaping air can create some thrust.
 
yeah...i did c that video.. thanks bro.. a lot.. dats a gud idea.. i'll try it.. any suggestion on how to decease floor to cd base resistance... .. we'll be testing for the displacement on tiles floor, which is very smooth and shiny..
