What Is Monty the Monstar Instant Slime?

Monty the Monstar Instant Slime is a slime powder that you simply add to water to create thick, oozy slime – perfect for:

• School fun runs
• Slime reward days
• Colour and slime events
• Youth group nights
• Fetes, carnivals and discos

It comes in our fun Monty the Monstar packaging, so it looks just as exciting on the shelf as it does in the tub. Kids recognise Monty from our fun runs and get instantly excited when they see him on the slime packets.

 

What You Need to Make the Slime

Before you start, grab:

• Monty the Monstar Instant Slime powder
• A large tub or container (or a few smaller ones)
• Clean water (buckets work well for larger events)
• A stirring paddle, stick or large spoon
• Measuring jugs or buckets (to keep your ratios consistent)

Tip: Always use the instructions on your packet for the recommended slime powder-to-water ratio, as it may vary depending on how thick or thin you want it.

 

Step-by-Step: How to Make Monty’s Instant Slime

Follow these simple steps for perfect slime every time:

1. Add the slime powder to the tub
   Sprinkle Monty the Monstar Instant Slime powder into the tub.
2. Add water to your tub
   Slowly add the water into your tub or container while stirring continuously at first to mix and help avoid clumps.
3. Stir, stir, stir
   Keep adding the rest of the water and mix until all the powder is fully combined and there are no dry patches or lumps.
4. Let it thicken
   Allow the slime to sit for a few minutes. It will begin to thicken and transform into gooey, slippery slime.
5. Give it a final mix
   Stir again to check the texture. If you want it a bit thicker, you can add a touch more slime powder. If it’s too thick, add a little extra water and mix through.

That’s it – your instant slime is ready!

 

Fun Ways to Use Slime at Your Event

One of the best things about Monty the Monstar Instant Slime is how versatile it is. Here are some popular ways schools and groups like to use it:

1. Slime Pits

Create a slime pit as a main attraction or as the grand finale to a fun run.

• Set up a shallow, sturdy tub or inflatable pool
• Mix a large batch of slime
• Let kids jump, crawl and splash through the slime
• Great for finishing lines, photo backdrops and reward activities

2. “Slime the Teacher” or “Slime the Principal”

Turn slime into a fundraising incentive:

• Set a fundraising target or goal
• If students hit the target, a teacher, principal or favourite staff member gets slimed
• Do the sliming live at assembly, during a fun run, or as part of a reward day

This is a simple idea that creates huge excitement and motivates students to get involved.

3. Slime Battles with Slime Blasters

Take your event to the next level with slime blasters and slime battles:

• Load slime blasters with slime for safe, supervised “battles”
• Run team vs team, class vs class, or students vs teachers
• Use it as a finale for fun runs, sports days or disco events

Kids love the action, and it creates unforgettable photos and videos.

4. Stage Games & Assemblies

Use slime in gameshow-style challenges:

• Slime for the losing team in a quiz
• Slime for brave volunteers from each class
• Slime as a surprise twist during assembly

The suspense and “who’s getting slimed?” question always gets the crowd buzzing.

 

How Much Slime Do I Need?

How much slime powder you need depends on:

• How many students are participating
• How you’re using the slime (pit, battle, or single slime moment)
• Whether students are going through slime or just watching someone be slimed

If you’re not sure, we’re happy to help.
