Watery Slime:

This causes the slime to be soupy and runny, making it difficult to work with.

Reasons for watery slime

  • Not enough slime activator was used
  • Excess liquid or too much water was added

How to fix watery slime

If your slime is too watery, there are a few things you can do to fix it. Check out the tips and tricks below on how to rescue slime.

1. Add more glue: The first thing you can do is add more glue to the slime. This will help to thicken slime and make it less soupy.

2. Add more Borax: If adding more glue doesn’t seem to be working, you can try adding more Borax to the slime. This will help to thicken borax slime, firm it up and make it less runny.

3. Add more liquid starch: If you’re using liquid starch as your slime activator, you can try adding more of it to the slime. This will help to firm it up and make it less runny.

4. Add baking soda: Baking soda is a common ingredient for thickening slime. Try adding 1/2 teaspoon at a time until the desired consistency is achieved.

5. Stir it longer: Sometimes, all you need to do is stir the slime for a longer period of time. If you didn’t stir it enough when you were making it, this can cause it to be too watery. Just keep stirring until the slime comes together and forms a cohesive ball.

6. Let it sit: If your slime is still too watery, you can try letting it sit for a while. This will allow the excess water to evaporate, leaving behind a thicker, more manageable slime. Just leave it out on a flat surface for an hour or so and check back periodically to see if it’s reached the desired consistency.

Hard Slime:

This is the opposite problem of watery slime and causes the slime to be too hard and difficult to stretch.

Reasons for hard slime:

  • Too much activator was used (too much liquid starch, too much baking soda)
  • Not enough water was added

How to fix hard slime:

To make your slime soft, here are a few things you can try doing:

1. Add more water: The first thing you can try is adding more water to the slime. This will help to thin it out and make the slime flexible.

2. Add extra shaving cream: Adding shaving cream can also help to soften hard slime. Just add a little at a time until the desired slime consistency is achieved.

Sticky Slime:

Sticky slime is a common slime fail that can make the slime difficult to work with and cause it to stick to everything it touches.

Reasons for sticky slime:

Not enough activator was used
Not letting it sit long enough

How to fix sticky slime:

If your slime is too sticky, there are a few things you can do to fix it. Check out the tips and tricks below on how to rescue slime:

1. Add morepolymer: The first thing you can try is adding more of the polymer to the slime. Some examples of polymer include Borax, liquid starch, and laundry detergent. This will help to absorb some of the excess moisture and make the slime less sticky.

2. Let it sit: If your slime is still too sticky, you can try letting it sit for a while. This will allow the excess moisture to evaporate, leaving behind a less sticky slime. Just leave it out on a flat surface for an hour or so and check back periodically to see if it’s reached the desired consistency.

Lumpy Slime:

Lumpy slime is another common slime fail that can make the slime difficult to work with. It can cause the slime to be lumpy, dry, and crumbly.

Reasons for lumpy slime:

Not enough activator was used
Too much glue was used

How to fix lumpy slime:

There are a few things you can do to fix lumpy slime. Check out the tips and tricks below on how to rescue slime:

1. Add more activator: The first thing you can try is adding more of the activator to the slime. This will help to bind the ingredients together and make the slime less crumbly.

2. Knead it: If your slime is still too crumbly, you can try kneading it. This will help to break up the lumps and make the slime more pliable.

3. Let it sit: If your slime is still too crumbly, you can try letting it sit for a while. This will allow the excess moisture to evaporate, leaving behind a drier, less crumbly slime. Just leave it out on a flat surface for an hour or so and check back periodically to see if it’s reached the desired consistency.

4. Add more glue: If adding more activator doesn’t seem to be working, you can try adding more glue to the slime. This will help to bind the ingredients together and make the slime less crumbly.

5. Add more water: If your slime is still too crumbly, you can try adding more water to the slime. This will help to soften it up and make it more pliable.

There are a few things that can cause slime fails. Here are some tips on how to avoid these issues:

The Ultimate Guide to Making Homemade Slime + How To Fix Slime - SUPA STEM (5)

1. Make sure all of your ingredients are properly measured to avoid an unfavourable chemical reaction. Too much or too little of any ingredient can cause the slime to be too runny or not form at all.

2. Make sure to mix and knead the slime thoroughly. This will ensure that the ingredients are properly combined and the slime is the right consistency.

3. Be patient! If your slime is too runny, let it sit for a while and it will thicken up. If your slime is too hard, add more glue or water until it reaches the desired consistency.

4. Store slime in an airtight container to keep it from drying out or becoming too hard.

With these tips, you should be able to fix any slime fail and have perfect slime every time!
